Temper is a compact, low power temperature sensor based on ESP8266 and SHT30 with large 13x7 pixel led display.
- Low power, only consumes ~30-40uA while asleep. With 400mA battery it should last months on single charge.
- SHT30 provides very accurate, factory calibrated measurement capability.
- Super simple Web config (see screenshot here)
- Home Assistant compatible including auto-discovery, but can be used with any other platform supporting MQTT.
- 13x7 pixel led display
- TP4054 charging IC onboard for easy charging via USB
- Can be attached to a wall using magnets (see thingiverse for details).
- After it's set up in config portal, it periodically wakes up and publishes Temperature, Humidity and Battery percentage through MQTT
- Pushing the reset button will force send current data and show Temperature on the display
- Hot air station / reflow oven (SHT30 has pins at the bottom, can't be hand-soldered)
- Components listed in "PCB and BOM" directory (lcsc and aliexpress links provided)
- Plastic case (download on thingiverse)
- Hot glue to fixate pcb in the enclosure
- Patience
- You can order it with most of the components pre-assembled from JLCPCB (you can find Pick&Place + BOM + Gerber in the above mentioned directory). Partially assambled pcbs will cost you little over $60 for 10pcs, see components information in "PCB and BOM" directory.
