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”.
