Heat Cost Allocator with wM-Bus at 868 MHz Reference Design
Description
The TIDA-00838 reference design implements a heat cost allocator system following the EN834 standard with the “two-sensor measurement method. The solution achieves better than 0.5 degrees Celsius accuracy across a range of +20 to +85 °C. Two analog temperature sensors are available as matched pairs to eliminate the need for calibration during manufacturing and lowering OEM system cost. Wireless MCU offers wM-Bus support for S-: T- and C-modes (Meter device) at 868MHz and controls the two temperature sensors."
Features
- Highly accurate temperature sensing across environment conditions: better than 0.5 degrees from +20 to +85 °C.CC1310 SimpleLink(TM) Wireless MCU provides single-chip solution for heat measurement and RF communicationsSensor Controller interfaces seamlessly to two matched LMT70A: which eliminate the need for calibration during manufacturing and lower OEM system costExample source code for wM-Bus @868 MHz transmission for S: T and C-modes (“Meter” device) under TI RTOSCost-optimized 2-layer PCB in HCA form factor and a 96-segments 4-MUX LCDCap Touch button on the PCB for LCD on/off
