Grove Infrared Temperature Sensor for Arduino

The Seeed Studio Grove Infrared Temperature Sensor provides non-contact temperature measurement for Arduino projects. It uses 116 thermocouple elements on a floating micro-membrane to detect thermal radiation. The sensor outputs an analog voltage from 0 to 1.1V corresponding to the target temperature. It suits makers building motion detection or industrial automation systems.

Grove compatible interface with low power draw

A Grove connector ensures plug-and-play integration without soldering or complex wiring. The module operates on a 3.3V or 5V supply and draws only 160 to 200 uA during measurement. Power consumption stays below .6mW, making it suitable for battery-powered devices. Its compact 130mm by 80mm by 11mm form factor fits easily into tight enclosures.

Measures -10 to 100°C at 9CM distance

The single specification that defines suitability is the measuring range of -10 to 100°C with a 9CM detection distance. Accuracy is rated at ±2°C with a two-second holding time. It operates reliably between -10 and 80°C and stores safely from -35 to 80°C. Buyers needing higher precision or longer range should consider alternative sensor types.

Questions about this item

What does the Grove compatible interface cap in practice for this sensor?

The Grove interface supplies 3.3V or 5V and delivers an analog voltage output of 0 to 1.1V that represents the measured temperature.

What are the physical dimensions needed to fit or mount this sensor?

The module measures 130mm by 80mm by 11mm and includes a Grove connector for direct plug-in mounting.

How is this sensor installed and what step is often missed?

Connect the Grove cable to a 3.3V or 5V port, allow the 2-second holding time for each reading, and ensure the target is within the 9cm measuring distance.
