Texas Instruments CC1310F128RGZR | Demoboard TIDA-00646
Matched Precision Temperature Sensing Reference Design for Heat Cost Allocators
Overview
| Topology | Wireless Power Transfer |
| IC revision | 1.0 |
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
Remark: BOM and Schematics are added with main pdf.
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
