The M5Stack T-Lite is a compact and easy-to-use WiFi thermal imaging camera that provides access to real-time thermal images from anywhere.
When I worked in construction, I had the chance to “play” with thermal imaging cameras. Besides their usefulness, I must say they are one of the most fun machines we can use.
However, traditional equipment is extremely expensive and out of reach for the domestic sector. Recently, however, several devices within the DIY range for thermal imaging have appeared.
This time, M5Stack presents its thermal imaging camera. To do this, in my opinion intelligently, they have decided to base it on their M5 Stick Plus device. As you know, at the moment, the M5 Stick Plus is my favorite device for #maker projects.
As we saw, the M5 Stick Plus is a device that mounts a dual-core ESP32-PICO at 240MHz, 600 DMIPS, 520KB SRAM. It incorporates a 1.14” TFT screen with 135x240 pixels.
Furthermore, it has an integrated 160mAh 3.7V battery. Power is supplied via the USB-C port, and it has an internal chip to manage charging.
Regarding other peripherals, the M5Stack T-Lite features an SPM1423 microphone and a passive speaker. However, it omits the 9-axis IMU found in the standard M5 Stick Plus.
As for the thermal imaging component, the T-Lite mounts a Melexis MLX90640-BAA sensor with a resolution of 32x24 pixels and a 110º FOV. The measurement range is from -40°C to 300°C, with a resolution of +/-1.5°C.
Both devices, the M5 Stick Plus and the thermal sensor, are housed in a single casing with a compact and lightweight design measuring only 69 x 26.6 x 6.35 mm and weighing 30.1 grams, making it easy to carry. 
We can view the thermal sensor both on the device’s TFT screen and via real-time streaming to a computer or mobile phone.
Obviously, we are dealing with a domestic thermal imaging camera, and we cannot expect the performance of an industrial camera costing several hundred (or even thousands) of euros.
However, it is a very fun and interesting device that we can use in projects such as non-contact temperature measurements, temperature anomaly monitoring, intrusion/motion detection, or checking electronic circuits.
The price is $79, excluding shipping costs. All information and code examples are on the product page at m5-docs
