8×8 thermal array for presence detection
The ET-S36 is built around the Panasonic AMG8833 — 64-pixel (8×8) thermopile, 60° FoV, 0–80°C, ±2.5°C, human detection ~7m, 10fps. It connects over I²C 0x68 / 0x69 (JP3) (400kHz) and is powered from VIN 3.3–5.5V, onboard LDO (sensor 3.3V, 4.5mA).
Two Qwiic / STEMMA QT connectors let you chain it with other boards without soldering, and the 2.54 mm header fits a breadboard.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Presence detection without a camera
- Low-res thermal imaging
- Counting people
