Matched Precision Temperature Sensing Reference Design for Heat Cost Allocators

Overview

TopologyOther Topology
IC revision1.0

Description

The TIDA-00646 reference design demonstrates techniques for precision temperature sensing as required by heat cost llocators and other Internet of Things (IoT) applications. Heat cost allocators use the temperature differential between Room and Heater body to assign a share of the total cost of a central heating system among multiple users. TIDA-00646 achieves better than 0.5 degrees Celsius accuracy across a range of +20 to +85°C. The LMT70A CMOS sensors used in the design are available as matched pairs to eliminate the need for calibration during manufacturing, lowering OEM system cost. The design is compliant to the EN834 standard using the “two-sensor measurement method”.

Features

Highly accurate temperature sensing across environment conditions: better than 0.5 degrees from +20 to +85degCMatching of two adjacent LMT70A sensors on Tape and Reel saves test and manufacturing costCC1310 SimpleLink(TM) wireless MCU provides single-chip solution for heat measurement and RF communicationsLow power operation down to 2.0V extends battery lifetimeCost-optimized two-layer PCB layout in HCA form factor

Typical applications

  • Precision Temperature Sensing With Matched CMOS Sensors in Any Wireless Application
  • Heat Cost Allocators With w-MBus RF Protocol at 868 MHz up to 15-dBm Transmit Output Power
  • Internet of Things and Wearable Applications With
