The PerkinElmer A2TPMI sensor module is an integrated thermopile sensor with signal‑processing, temperature compensation and programmable output options.
About this manual
The A2TPMI combines a thermopile detector with on‑chip signal processing and an environmental temperature sensor, providing both target and ambient temperature outputs. It supports analog voltage, comparator mode and serial configuration via a two‑wire SDAT/SCLK interface.
The module is supplied in a TO‑39 6‑pin package, offers programmable gain, bias and comparator thresholds, and includes an on‑board EzPROM for user‑defined settings. Electrical specifications cover a 5 V supply, wide input voltage range, and built‑in reference voltage of 1.225 V. This manual is written in Chinese.
