Ürün Açıklaması

Laser module USB arduino precise distance measurement M703A
Chengdu JRT Technology Co., Ltd. is a production factory specialized in R & D, production and sales of ranging sensors. The measurement accuracy is generally in the millimeter level. It can accurately measure the distance of target objects. Laser ranging sensors can also be used to measure targets. Length, width and height can be applied to the field of automated measurement.
Chengdu Jingruite Technology Co., Ltd. was founded in 2004. Since its establishment, the company has been focusing on the R & D, manufacturing and marketing of laser ranging products. The main products are industrial laser distance sensors, tof distance modules, and laser ranging module.
Advantages of laser distance sensors:
1. Laser ranging sensor, non-contact measurement.
2, the whole accuracy error of 1 mm.
3. The continuous service life of the laser is more than 5000 hours.
4, with standard RS232, RS422 communication serial port.
5. Simple and practical communication software guarantees accurate and convenient work on site.

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: ±1mm+40PPM.
2.Under strong light or bad diffuse reflectance of target, please use a reflector.
3.Operating temperature -10 ºC~50 ºC can be customized.
4.U81 supports multi-slaves network.

Why choose our laser ranging sensors?
1. Multiple communication interfaces: serial port / RXTX / USB / RS232 / RS485.
2. High precision. The accuracy can reach ± 1mm.
3. Multiple function design. Support continuous measurement.
4. Remote. Compared with traditional tape measure, our laser rangefinder can have a longer range, up to 150m.
5. Easy to use, compact and easy to install. We provide detailed instructions and technical guidance to help you better use the laser ranging module.
6. Safety. Using a laser rangefinder is much safer than using a tape measure because the user does not need to climb up and down.



 

Pin Information:

Hardware Connections
1. Hardware Interface: 2 line USART(Rx, Tx);
2. Baudrate: 19200bps;
3. Data bits: 8b;
4. Parity: none;
5. Flow control: none.
 
Power On Sequence:
1. Controller power on the module;
2. Wait 100ms or above to make sure module properly initialized;
3. Module will send back sting ",OK!" as Ready To Go signal.
 
Normal Operations Sequence:
1. Controller sends out the operation command(single byte ASCII);
2. Echo command from module to indicate command has been received and now in progress;
3. Command result from module.
 
Single Byte ASCII Control Commands:
1. 'O'(0x4F): Turn ON laser beam, module turn on the laser and return ",OK";
2. 'C'(0x43): Turn OFF laser beam, module turn off the laser and return ", OK";
3. 'S'(0x53): Module status read, module returns Temperature& Battery Voltage, e.g.: "18.0'C, 2.7V";
4. 'D'(0x44): Distance read, module returns Measure Result & Signal Quality(SQ), e.g.: "12.345m, 0079", smaller SQ value stands for more reliable distance result.
