Out of stockOverview
Medical-grade accuracy digital temperature sensor
The ET-S16 is built around the TI TMP117 — ±0.1°C (−20…50°C), 16-bit, 0.0078°C resolution; meets ASTM E1112 / ISO 80601 (clinical thermometry). It connects over I²C 0x48–0x4B and is powered from VIN 1.8–5.5V direct (no LDO, which also removes LDO self-heating).
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
- Precision temperature logging
- Calibration references
- Lab and incubator monitoring
