80m RS232 Long Distance Sensing Sensor

80m RS232 Long Distance Sensing Sensor

Dear Sir/Madam, 
Are you looking for using one of our Laser Distance Sensor Modules in combination with a single-board computer (e.g. Raspberry Pi) on a prototyping project? Yes, the B87A with RS232 can be use to coonect to your computer. The long distance sensing sensor is to measure distances up to 80m with an accuracy of +-3mm or better in an absolute dark environment with a temperature between -10°C and 50°C. Welcome to contact for more details.
FAQ for purchasing manager：
1. Q: I am intersting to this item, can you send me one sensor for testing in my project? 
   A: Yes, the MOQ of our sampele order is 1 unit, please provide your address to check the cost for you.
1. Q: I want to test it on my computer, can you tell me which model is suitable?
   A: USB or RS232 optional.

How to work

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.
