This is a non-contact IR temperature sensor which uses Infrared radiation to calculate the temperature of something at which it is pointed.
- Voltage range: 3.3-5V
- Temperature range: -70 to +380 °C, (0.01 ℃ resolution)
- Measurement Accuracy: ±0.2℃(body temperature range)/ ±0.5℃ (ambient)
- Chip: MLX90614 with 17 bit Analogue to Digital (ADC) Converter
This sensor requires the Pin swap module to be inserted between two 4-wire jst leads connecting the peripheral to the Kookaberry. This is because the pin arrangement on the sensor module does not match the pin arrangement on the Kookaberry
How does it work?
The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing, and output module.
The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted into corresponding electrical signals when converging on the photoelectric detector.
After being processed by the amplifier and signal processing circuit, the signal is converted into a temperature value. The MLX90614 integrated circuit chip is self calibrating and has a low noise amplifier integrated into the signal processing chip. The chip itself is a 17 bit ADC and DSP device, giving accurate and reliable results.
Where are they used in real life?
The most visible use is for the rapid measurement of body temperature. They are also used in a range of industrial applications where hot spots can indicate trouble – like an overheating bearing in a motor
