Introduction
The STMicroelectronics VL6180X Time of Flight Ranging Sensor embeds ST’s patented FlightSense™technology that allows distance to be accurately measured independent of target reflectance. The sensor is rated to perform ranging measurements of 5-100mm, but it can provide readings up to 200mm in a good environment. Besides, VL6180X is also equipped with an ambient light sensor, so basically, this is a sensor that combines proximity ranging and ambient light level measurement capacities into a single package.
Features
- Simultaneous measurement of distance and ambient light
- VCSEL light source
- Strong anti-interference
Applications
- Short distance measurement applications
- Robot obstacle detection
- Distance trigger switch
Specification
- Power Supply Voltage: 3.3V~5V
- Operating Current: <5mA
- Measuring Distance: 5-100mm
- Emitter: 940 nm invisible laser (VCSEL)
- I2C Address: 0x29
- Operating Temperature Range: -20℃~85℃
- Product Size: 19x18mm / 0.75x0.71 inch
