This innovative sensor can detect infrared radiation in the 2µm to 22µm range (the range of radiant heat). The device consists of a PCB on which is an array of eight thermopiles (thermocouples connected in series), together with a silicon lens and associated electronics. The sensor can simultaneously measure the temperature of eight adjacent points, as well as controlling a servo. When used in a relevant robotic application, servo control will enable a thermal image to be built up over a wide field of view.

  • Suitable for many applications include robotics and security
  • Detects body heat
  • Will detect a candle flame at 2m
  • Unaffected by ambient light
  • Only requires 5V supply
  • All communications by I2C bus via standard I2C 5-pin connector
