The TMP107 digital output temperature sensor supports a total of 32 daisy-chained devices. Each sensor has a unique 5-bit address stored in electrically-erasable programmable memory (EEPROM). The TMP107 is capable of reading temperatures with a resolution of 0.015625°C, and is accurate to within ±0.4°C in the range from –20°C to +70°C. The TMP107 is ideal for replacing NTC and PTC thermistors where high accuracy is required.

The unique 5-bit address stored in the EEPROM is determined during the automated address assignment operation, and is based on the position of each sensor relative to the SMAART wire host. Multiple operating modes provide maximum flexibility in selecting between low power consumption for battery operation, and high update rates for real-time control applications.

The TMP107 is ideal for extended temperature measurement in a variety of industrial, instrumentation, communication, and environmental applications. The TMP107 is available in an 8-pin SOIC package and is specified for operation over a temperature range of −55°C to +125°C.

參考設計

TIDA-00800 — 適用於 SensorTag 的菊輪鍊溫度感測器參考設計

TIDA-00800 參考設計在佈線環境中採用菊鍊連接的 4 個溫度感測器。  這些感測器透過 UART 介面連接到 SensorTag 開發平台，資訊可以透過此介面進行無線傳輸。  由於藍牙低功耗無線技術已整合到大多數現代設備中，因此使測試和演示變得更加容易。  外型尺寸和電氣連接與 TI SensorTag 2.0 生態系統相容，可輕鬆與其他無線技術 (Zigbee、Wifi、Sub-1 GHz…) 進行原型設計，同時所選感測器可實現工業級的準確度和解析度。
