Product Description

JRT 30m arduino Laser Distance Sensor RS232

JRT 30m arduino Laser Distance Sensor RS232 the size of 41*17*7mm with RS232  is a mini laser ranging sensor, so it is every small and convenient. It model number is U81, the measuring range is 0.03-30m without reflection, measuring time is 0.1~4 seconds.  Because of the laser sensor with USB is small and portableand ,wide scope of application and high accuracy more and more customers  like them. For different range measuring program, our modules can satisfy customers different requirements, 30m, 40m, 60m, 80m, 100m, 120m, 150m, each distance can be multifunctional, such as:Height/Distance/Area/Volume/Pythagorean Measurement. Voice, Bluetooth, angle measuring, beep, and any other functions can be customized. We have been in this laser line for over 15 years, with a strong R&D ability through unremitting efforts, we are now a leading supplier of laser distance meter modules in China.
