# Temper-ESP8266

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](https://github.com/mcer12/Temper-ESP8266/wiki/Config-portal-&-OTA))

- 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).

## How does this thing work?

- 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

## What you need to make it yourself

- 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](https://www.thingiverse.com/thing:4126709))

- 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.
