Wireless Thermocouple Sensor Transmitter DevPack for SensorTag Reference Design

TIDA-00650

Design files

Overview

The TIDA-00650 reference design shows how to build a wireless thermocouple based temperature transmitter. The design is in the DevPack form factor which can be used in combination with TIs SensorTag. This allows for the development of a wireless link with Bluetooth® Smart or other wireless technologies (Zigbee, WiFi, sub 1GHz). The 24-bit ∆Σ sensor front-end utilized in this design allows for operation over the -40 to +85C temperature range.

Features
  • Wireless (isolated) Thermocouple Sensor Transmitter
  • 24-bit ∆Σ sensor AFE
  • Bluetooth Smart Interface
  • Type-K TC sensor with PT100 Cold-Junction Compensation
  • TC Temperature Range: -270°C to 1372°C
  • Operating Temperature Range: -40C to +85C

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
