BAPI 50223 Wireless Duct Temperature and Humidity Sensor

Product Information

The Wireless Duct Temp/Humidity Sensor by BAPI is designed to measure environmental values and transmit the data via Bluetooth Low Energy to a receiver or gateway. It features a rugged IP66-rated BAPI-Box enclosure, ensuring durability in various conditions.

This wireless sensor is equipped with adjustable settings that can be field adjusted to suit the needs of the installation. These settings can be configured using either the gateway or the receiver.

The sensor can be used with two different devices:

• Receiver (Wireless-to-Analog): This wireless receiver from BAPI receives data from one or more wireless sensors. It then transfers the data to analog output modules, converting it into an analog voltage or resistance. The receiver supports up to 32 sensors and up to 127 different analog output modules.
• Gateway: The wireless gateway from BAPI receives data from one or more wireless sensors and provides it to the cloud via MQTT. It also sends a confirmation signal to each sensor upon successful reception of data. The gateway supports up to 32 sensors.

To establish communication between the sensors and the gateway or receiver, refer to BAPI’s Wireless Quick Start Guide or the gateway/receiver instructions available on the BAPI website.

Adjustable Settings
BAPI’s wireless devices have several settings that can be can be field adjusted to suit the needs of the installation. All settings are configured by either the gateway or the receiver. (See the gateway or receiver instructions documents available on the BAPI website for more information on adjusting the settings.)

• Sample Rate/Interval – The time between when the sensor wakes up and takes a reading. The available values are 10 sec, 30 sec, 1 min, 3 min or 5 min with the gateway, or 30 sec, 1 min, 3 min or 5 min with the receiver.
  Transmit Rate/Interval – The time between when the sensor transmits the readings to the gateway or receiver. The available values are 30 sec, 1, 2, 3, 4, 5, 10, 15, 20 or 30 minutes, or 1, 6 or 12 hours with the gateway, or 1, 5, 10 or 30 minutes with the receiver.

• Delta Temperature – The change in temperature between sample intervals that will cause the sensor to override the transmit interval and transmit the changed temperature at the next sample interval. The available values are 0.1, 0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5 °F or °C with the gateway, and 1 or 3 °F or °C with the receiver.

• Delta Humidity – The change humidity between sample intervals that will cause the sensor to override the transmit interval and transmit the changed humidity at the next sample interval. The available values are 0.5, 1, 2, 3, 4 or 5 %RH with the gateway, and 3 or 5 %RH with the receiver.

• Temperature Min/Max – The maximum or minimum temperature that will cause the sensor to override the transmit interval and immediately transmit a reading to the gateway. (Only available when using a gateway.)

• Temperature Offset – Adjusts the temperature value being transmitted to match that of a calibrated reference device. The available values are ±0.1, 0.2, 0.5, 1, 2, 3, 4 or 5 °F or °C. (Only available when using a gateway.)

• Humidity Offset – Adjusts the humidity value being transmitted to match that of a calibrated reference device. The available values are ±0.5, 1, 2, 3 or 5 %RH. (Only available when using a gateway.)

Initial Activation

Battery Power Units
The unit comes with two pre-installed batteries. To activate the unit, open the cover to access the batteries. Find the battery tab insulators and pull them out. Press the Service button and the Service LED should flash once to confirm power.

Wire Power Units
To activate the unit, open the cover to access the circuit board and apply the 9 to 30 VDC or 24 VAC to the power terminals as shown. Press the Service button and the Service LED should flash once to confirm power.

Mounting

1. Place the sensor in the middle of the duct away from temperature stratified air, coils or humidifiers to achieve the best reading.
2. Drill 1” (25mm) diameter probe hole and insert the probe into the duct. Use the enclosure tabs to mark the pilot hole locations and drill the 1/8” (3.2mm) pilot holes. Mount the enclosure to the duct using the provided mounting screws.
3. Tighten the screws until the foam backing is depressed slightly to prevent air leakage.

Operation

Power the unit as described in “Initial Activation” section. Follow the gateway or receiver instructions for pairing the unit and changing the adjustable settings. (The instructions are available on the BAPI website.)

Wireless Sensor Reset
Sensors remain paired to the gateway or receiver and output modules when power is interrupted or the batteries are removed. To break the bonds between them, the sensors need to be reset. To do this, press and hold the “Service Button” on the sensor for about 30 seconds. During those 30 seconds, the green LED will be off for about 5 seconds, then flash slowly, then begin flashing rapidly. When the rapid flashing stops, the reset is complete. The sensor can now be paired to a new receiver or gateway. To re-pair to the same receiver or gateway, you must reset the receiver or gateway. Output modules that were previously paired to the sensor do not need to be re-paired.

Onboard Memory
Sensor retains up to 16,000 readings should the communication become interrupted. The sensor only stores readings from missed transmissions and only when the sensor is paired to a gateway. Once communication is re- established with the gateway, the stored readings are transmitted and then erased from the sensor. The current reading and nine previous readings are sent at each transmit interval until the sensor is caught up.

Battery Replacement
Open the cover to access the batteries (Fig 6).
Remove the batteries from their holders and discard in an environmentally safe manner. Replace with new batteries in the correct orientation.
