Module caméra thermique Guide Sensmart M2SA 256x192 pixels -20 à 150 °C

The Guide Sensmart M2SA is a compact thermal imaging camera module that connects to a smartphone via USB‑C and delivers 256×192 thermal resolution with autofocus and a 25 Hz frame rate. Designed with a metal housing and graphite finish, the M2SA operates over a temperature range of -20 °C to 150 °C with measurement accuracy of ±2 °C (or ±2%) and provides night vision capability up to 100 m. Battery‑free and lightweight (0.04 kg), it is intended for portable inspections and diagnostics using your phone as the display.

Advantages

The M2SA combines a WLP autofocus infrared module with professional‑grade 256×192 resolution to produce clear thermal images comparable to larger devices while remaining small and easy to carry. It draws power directly from the smartphone, eliminating the need for an internal battery. With a 25° field of view, 25 Hz image frequency and a durable metal housing, the device supports repeated field use and delivers reliable temperature measurements for a variety of inspection tasks.

How to use

Connect the Guide Sensmart M2SA to a compatible smartphone using the USB‑C connector and launch the corresponding app. Allow the module to autofocus on the target; the device provides live thermal imagery on the phone screen at 25 Hz. Move the camera to scan surfaces or components, pausing to record images or temperature readings as needed. For accurate temperature measurement, ensure the target fills a sufficient portion of the frame and avoid obstructions between the camera and the target.

Recommendations

For best results, calibrate measurements against a known reference when high absolute accuracy is required, maintain a clear line of sight to the target, and avoid rapid changes in ambient temperature while measuring. Store the unit in its carrying case when not in use and protect the lens from impacts and contamination.
