Response to confetti：
PWM output
n PWM mode, the sensor outputs a PWM signal through the PWM port (pin 3). The PWM period is 500mS, and the level is calculated according to the low level width. Levels 1-4 correspondto100-400mS respectively. The low pulse width of the pin output corresponds to the sensor level value. The level value is internally processed by software filtering, and the beating a amplitude is relatively small. If the optical path of the sensor is seriously blocked, which affects the measurement, the sensor will output a PWM with a period of 500mS and a low-level width of 495mS until the optical path of the sensor returns to normal.
Remarks： 1.low pulse width 100ms = 1 grade。
UART output
In serial port mode, the sensor outputs serial port data through the TXD pin (pin 3), and send saframe of data every 500mS.
Serial port general settings:
| Baud rate | 9600 |
|---|---|
| Interface level | 4.4±0.2 V(TTL) |
| Data byte | 8 bytes |
| Stop byte | 2 byte |
| Check byte | no |
Cautions
Installation:
- The installation position of sensor transmitter and receiver should be designed at 180°±10°
- In order to ensure accuracy and consistency, the distance between the launch tube and the receiver should not be too long (recommended less than 60mm)
- External light and foreign objects should be avoided in the optical beam area
- The sensor’s location should avoid strong vibration
- The connection between the receiver and the sensor motherboard should avoid strong electromagnetic environment. When there is a wireless communication module (such as WiFi, Bluetooth, GPRS, etc.) around the sensor, it should keep a sufficient distance from the sensor. Please verify the specific safety distance by yourself.
Transport & storage：
- Avoid vibration – During transportation and assembly, frequent and excessive vibration will caused is location of optoelectronic devices and affect the original calibration data.
- Long term storage – Store in a sealed bag to avoid contact with corrosive gases to damage circuit board sand optical devices
