Global Overview
The 65X1N Wireless Pressure Sensor operates as a smart device, offering sensor acquisition, processing capabilities, analysis, and wireless communication capabilities. The device computes pressure or internal temperature data using slope detection and raw data. Thresholds can be configured, and data can be sent over BLE advertisement. BLE is used for sensor configuration and accessing other features such as datalog and live data.

The product has two BLE modes:

• Advertisement Mode: Provides data periodically.
• Connected Mode: Mode for configuration and advanced features. Switching to Connected mode is only possible through an advertisement.

Measurement Process
The platform acquires digital data from the sensor using a separate power supply at 2.8V. It communicates with the sensor via a communication bus (I2C or SPI) to read data from the sensor’s memory (data, calibration, etc.). The system acquires and stores the data, applying sensitivity to the raw value.

Data Collection Diagram
At every measurement interval, the platform powers up the sensor and requests a new acquisition. The sensor provides data and temperature, which are then stored. When the measurement interval is changed, a new measurement is performed upon receiving the new value.

Data Process
No information is vided in the user manual.

GLOSSARY

• The sensor is the sensing element that transforms physical value to voltage It could have a digital or analog interface.
• The platform is the generic electronic software used to acquire data and send data over RF communication.
• The system is a combination of a sensor and a platform.
• Product is a specific system.

GLOBAL OVERVIEW

The system operates as a smart device. It offers sensor acquisition, processing capabilities, analysis, and wireless communication capabilities. Processing and analysis functions offer to the end user flexibility and cover most of the application.

The device computes pressure or internal temperature data partly:

• slope detection,
• raw data.

The threshold can be con The user has to choose between data to feed the threshold. BLE-only system, data are sent over BLE advertisement. BLE is used to configure the sensor and access others feature such as datalog and live data,…

The product has two BLE modes:

• Advertisement Mode: provides data periodically
• Connected Mode: mode for configuration and advanced features. Each advertisement allows the opportunity to user to switch to Connected mode. It’s the only way to go into connected mode.

MEASUREMENT PROCESS
The platform acquires digital data from the sensor. On acquisition chain system uses:

• Sensor power supplies: A separate power supply is used for the sensor at 2.8V
• A communication bus (I2C or SPI): It can read data from the memory of the sensor.(Data, Calibration,…)
• The system acquires and stores data.
• It applies sensitivity to the raw value

At every measurement interval, the platform powers up the sensor and asks for a new acquisition, and the sensor provides data and temperature. Both data are stored. When the measurement interval is changed a new measurement is done when the new value is received by the system.

DATA PROCESS

DATA PROCESSING

Slope
Time domain data are used to calculate the slope between two data.

TRIG MEASUREMENT COMMAND
When the BLE-connected mode is activated, the user can ask for a new measure without waiting measurement interval. After a Trig measurement command, the next measurement will happen after the measurement interval.

DATALOG DATA
The system stores in memory 4096 data. When the memory is full the oldest data store is replaced by the new one and so on.

Data stored in memory are available in BLE-connected mode.

LIVE MODE

• When connected mode is activated, the user can get access to a live mode. It will acquire data at a new measurement interval fixed at 100ms and provide all data to be available in “real-time”.
• When the user stops the BLE connection the system comes back to its current configuration and applies regular measurement intervals.

Note : if a threshold is reached during live mode the system will use a Threshold measurement interval otherwise it uses a standard measurement interval.

THRESHOLD EVENT MANAGER

The threshold event manager allows the user to have a specific configuration when a value reaches a level (main sensor and/or secondary sensor).

• Up/down Threshold:
  Every newly acquired value is compared to a threshold.

• Actions:
  When a threshold is reached, the system will set a flag. This flag is available on the advertisement frame. Upon user configuration, the system can change advertisement mode and measurement interval. This configuration can be done in BLE-connected mode.

• Behavior:
  This new configuration can last while the threshold is reached or until the user clears the Threshold flag. All this configuration can be done in BLE- connected mode.

At configuration, the user needs to define:

• Data to consider: Main sensor and/or Secondary sensor
• Data to use: Raw data and/or Slope
• Threshold: Level and type: up or down
• Event after threshold: Flag, Measurement interval, Advertisement mode

Every newly acquired value is compared to a threshold. On the threshold, the sensor will do a specific action and behaviour defined by the user:

• Set up flags to inform customers that a threshold has been reached
• Change BLE Advertisement mode (only on event mode activated)
• Change measurement interval (only on event mode activated)

If there are conflicts when several Threshold are reached:

• The system will use the lowest measurement interval and at each new threshold reached or released a new configuration analysis will be done
• The system will use first Periodic Mode and then measure mode

SYNC BETWEEN DIFFERENT SENSOR

If the user configuration can manage multiple BLE connections, the user can synchronize several sensors.

To achieve that user has to:

• Activate connected mode on several sensors
• Send a Trig measurement commasensorsall to send.

All sensors will be synchronized with a resolution of 1s. All measurements will be done during the same time slot.

COMMUNICATION: BLE

BLE is used to send data to a central acquisition system.

BLE provides 3 main states:

• Advertisement Mode : periodic data available
• Connected mode : advanced data analysis and sensor configuration
• Idle : low power mode with no activity

The product has several advertisement frequencies varying upon a time, configuration and hardware event:

FAST ADVERTISING PHASE: During 1 hour after power on. When the device is powered on, a yellow LED blinks to confirm the proper battery insertion. From the sensor startup and for 1 hour, the device advertises every 1 sec. This allows the user to configure the product by switching to connected mode. A measurement is performed at each measurement interval.

ADVERTISING MODE PHASE: 1 hour after power on

After the first hours, the system will apply configuration parameters such as ADV Mode. After every measurement, the device will advertise upon ADV Mode configuration:

• ADV Periodic Mode: (Default ADV mode)
  After each measurement, the sensor will send an advertisement every 1s interval for 15 seconds. This will give multiple chances for the gateway to connect to the device. After 15 seconds, the device will advertise at 10 intervals till the next measurement. During, this phase, the connection between the system and an external device could be more difficult. Between the two measurements, the data in the advertisement frames is the same. The payload is only updated after every measurement interval.

• ADV On Measure Mode:
  After each measurement, the sensor will send an advertisement every 1s interval for 15 seconds. This will give multiple chances for the gateway to connect to the device. After 15 seconds, the device will stop to advertise. This ADV Mode can be selected by using BLE services ADV_CFG for the current state and THS_ADV_MODE if a threshold is activated

• ADV Mute Mode:
  After each measurement, the sensor won’t send an advertisement. This ADV Mode can be selected by using BLE services ADV_CFG. This mode is not recommended if the threshold is not activated and THS_ADV_MODE is not configured. The only way to change the configuration over BLE is to use the magnet and activate the advertisement (see 3. Magnet Event).

Comparison of ADV mode
After a measurement, if a threshold is reached, the system will use threshold configuration (ADV mode and Measurement interval).

Magnet event:
If the advertisement interval is too long, it could be difficult to switch to connected mode. Our system offers the opportunity to advertise more often when the magnet is used. The magnet event will trigger a measurement and the device will advertise every second during 1hour. Users can therefore connect to the device.

Note : When the system detects a magnet event, the user has to wait 10s to achieve another magnet event.

DFU MODE: DEVICE FIRMWARE UPDATE

DFU mode should be used to upgrade the sensor firmware. It is accessible from the

The new firmware to be loaded must be signed by TE.

The DFU works with a single bank only. This means that if the firmware update is interrupted (power cut off or BLE disconnection), the application firmware will be corrupted, and the sensor will stay in DFU mode. The user will have to re-try the upgrading process. Note that the DFU MAC address is the sensor MAC address +1.

BATTERY

SAFT LS17330

The system should be exclusively powered with an LS17330 battery.

BATTERY LIFE

Depending on customer settings (measurement interval) battery life could go up to 4 years (depending on measurement interval and RF communication). The lower will be the number of measurements per day, the higher will be the battery life.

BATTERY REPLACEMENT
The system battery can be changed if empty. Unscrew the plastic housing and remove it from the base. Carefully use a small tool (such as a flat screwdriver) to take off the battery. Note that it MUST be replaced by the same battery reference (others may damage and/or bring uncontrolled behaviour of the sensor). Double-check the polarity and then insert the new battery inside the holder. Re-position the plastic cover on the sensor. Once done, the user must have to use the BLE “battery” characteristic value to reset the battery estimation algorithm.

This action is mandatory otherwise battery level will stay at 0%!

HIGH-LEVEL IMPLEMENTATION

Battery capacity baseline: 1.7Ah

Every action is transformed into energy and subtracted from the baseline. The battery voltage is used to check the 1% and 10% threshold to confirm the battery estimation. This threshold condition has priority.

Guards
The battery voltage is used to confirm the battery estimation. If 10% or 1% is detected using the cell voltage and confirmed 5 consecutive times. The guard ignores the estimation and only relies on the cell voltage.

MAGNETIC SWITCH

The system embeds an internal reed switch. This contactless button can be activated by approaching a strong magnet close to the magnetic sensor location. The magnetic switch location is indicated by the magnet drawing on the plastic housing.

Two different functions are available depending on the user’s action:

Activates BLE for another one hour plus trigs a new measurement.
