STMicro VL53L1X Time of Flight (ToF) Sensor Extends Distance Measurement Range up to 4 Meters
STMicroElectronics VL53L0X ToF (Time-of-flight) range sensor is a tiny chip that can accurately and quickly measure distance up to 2 meters using laser light. I had the chance to test the sensor via TinyLIDAR board connected Arduino and Raspberry Pi, and found it was a great little sensor. TinyLIDAR includes an STM32 MCU, but you can also find standalone board for as low as about $4 shipped on Aliexpress. However, if 2 meters is too short a range for your project, the good news is that STMicro has now launched VL53L1X ToF “FlightSense” sensor with a range of up to 4 meters. VL53L1X is pin-to-pin compatible with VL53L0X, so existing PCBs could be re-used with the new sensor. STMicro VL53L1X main specifications: Emitter: 940 nm invisible laser (Class1) SPAD (single photon avalanche diode) receiving array with integrated lens Low-power microcontroller running advanced digital firmware Distance Ranging up to 4 meters […]
