TIDA-00646, Matched Precision Temperature Sensing Reference Design for Heat Cost Allocators
TIDA-00646, Matched Precision Temperature Sensing Reference Design for Heat Cost Allocators. The TIDA-00646 reference design demonstrates techniques for precision temperature sensing as required by heat cost allocators 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. 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
