Meet Temper, a compact, low power temperature sensor based on ESP8266 and SHT30 with a large 13×7 pixel led display. It accesses WiFi periodically to display temperature and humidity data as well as battery percentage via the MQTT protocol. The device’s display uses three 74HC595 + 7 n-fets, TP4054 to handle battery charging through a USB and MCP1700T LDO to power the ESP. For WiFi setup, Temper …
