  • *Features: The infrared sensor module has a pair of infrared emitting tubes and receiving tubes. The infrared emitting tubes emit at a certain frequency. When the detection direction encounters an obstacle (reflective surface), it will be reflected to the infrared receiving tube. After being processed by the comparator circuit, the green indicator light will light up, and the signal output interface will output a digital signal (low-level signal).
  • *Usage: The OUT output sensor module can be directly connected to the microcontroller port and can directly drive 5V relays.
  • *Distance: The detection distance of the infrared module is 2 to 30 centimeters, the detection angle is 35 degrees, and the distance between the detectable potentials can be adjusted.
  • *Function: The infrared obstacle avoidance sensor module can be applied to robot obstacle avoidance, obstacle avoidance vehicles, line count, black and white line tracking, etc.
  • *Application: There is a red power indicator light, and the infrared sensor module can be applied to 3-5V DC power modules.

  • The ambient light sensor also has high sensitivity and under ultra-low light, wide sensing dynamic range, and ambient light () corrected output. All components used to support proximity sensors and ambient light sensors are integrated in a packaged optical module. The embedded design can be completed without the need for a mechanical spacer or an additional lens system.
  • The VL6180X module implements a proximity sensor with the time-of-flight (ToF) measurement principle; The VL6180X includes a SPAD detector array that detects the time at which a single photon is transferred from the target to the target and back to the module, calculated in combination with the amplitude. The actual distance, regardless of the reflectivity of the object, this actual distance measurement capacity can also produce simple but reliable one-dimensional gesture control.
  • The VL6180x three-in-one -electronic module integrates an IR VSEL (vertical-cavity -emitting laser) infrared vertical cavity -emitting source, proximity sensor, and ambient light sensor (ALS).
  • Product Parameters:Infrared wavelength: 850 nm;Communication interface: IIC (400 kHz), address 0x29 (7-bit), two programmable GPIO;Optimal working temperature: -10 ~ 60 Celsius;Range range: 0 to 100mm Error 13mm Under certain external conditions, such as 100mm in dark environments;Temperature drift: 9 ~ 15mm Voltage drift: 3 ~ 5mm
