Measuring range: 0.05~40m Resolution: 1nn Measurement accuracy: ±(1.5mm+d*50,000ths) Data output rate: Normal mode: 1~10Hz (usually 5Hz) Fast mode: about 10Hz/20Hz/30Hz Laser type: 630-670nm, Class II, Less than 1mW Indicator light: red laser Operation mode: single data/continuous data/external trigger Connector: dual-row 2.54-row jack Data interface: UART (3.3V TTL) two-wire serial interface (master mode reports measurement information) Communication protocol: serial port protocol Power supply: +5V Power consumption: Less than 1W Storage temperature range: -20℃ ~60℃ Operating temperature range: -15℃ ~ 50℃ Storage humidity: RH85% (1) Longer distances can be measured with a strong reflector. The range value can be set by downlink , and the maximum setting is 80 meters. (2) In harsh environments, such as outdoor sunlight, the performance be affected. It can be used with a target reflector to improve performance. (3) In fast mode, the return light is less than 50mV, and the error become larger. There are certain requirements for the measurement target and distance. It is not suitable for outdoor daytime applications.
