Compact 16x4 thermal sensor

This Grove module integrates the MLX90621 infrared array to deliver a 16 by 4 pixel thermal image over I2C. The sensor measures object temperatures from -40 °C to 300 °C with a calibrated accuracy of ±1 °C ±3 % of the difference between object and sensor temperature. Its 60 ° horizontal field of view suits close-range monitoring tasks. The board operates while the sensor temperature stays between -40 °C and 85 °C.

Makers adding heat vision to microcontroller

Hobbyists and engineers building thermal imaging into Arduino, Raspberry Pi or similar MCU platforms can connect the Grove cable and read frames directly via I2C. The low 16x4 resolution cannot resolve fine detail or serve as a security camera. Buyers who need higher pixel counts, radiometric video streaming or built-in display should look at dedicated thermal cameras instead.

60 ° horizontal field of view

The fixed 60 ° × 16 ° optics define how much of a scene fits into the 16x4 pixel grid at any distance. A wider FOV captures more area per frame but reduces the temperature detail per pixel. Verify that the angular coverage matches the monitoring zone you intend to scan before integrating the module.

Questions about this item

What size board and connector does the MLX90621 module need to fit a Grove port?

The sensor array is a 16x4 pixel IR camera that plugs directly into a standard Grove I2C socket, so it only needs the space for that 4-pin connector on your board.

How do I wire the thermal camera to my MCU and what step is often missed?

Connect the module to the MCU using the Grove I2C cable; the step people miss is allowing the sensor’s internal Ta reading to stabilise before taking the first frame.

What temperature extremes will the sensor itself survive in long-term use?

The MLX90621 is rated for an operating ambient range of -40 °C to 85 °C, so the module itself must stay within those limits during continuous operation.
