Notes:

1. Under bad measure condition, like environment with strong light or the diffuse reflectance of measuring point over-high or low, the accuracy would have bigger amount of error: ±1 mm+40PPM.

2. Under strong light or bad diffuse reflectance of target, please use a reflector.
3. Voltage can be changed by power converter LDO
4. Frequency would be affected by environment.
5. Operating temperature -10 ℃~50 ℃ can be customized.
6. Analog can be customized.

How to use your module to test?
There is a simple steps for you:
1. install the Gese software and USB driver on your computer.

2. Then you can send the related command to test

Communication
1.‘O’(0x4F): Turn ON laser beam, and return “,OK!”; 
2.'C'(0x43): Turn OFF laser beam, and return “, OK!”; 
3.'S'(0x53): Module status read, module returns Temperature & Battery Voltage, e.g.: “18.0’C, 2.7V”; 
4.'D'(0x44): Auto mode Distance read.

Hardware Connections 
1. Hardware Interface: 2 line USART(Rx, Tx); 
2. Baudrate: 19200bps; 
3. Data bits: 8b; 
4. Parity: none; 
5. Flow control: none.
