ESP Thermometer

thingiverse

I've built this Indoor case for my ESP32 Based Thermometer with precision engineering. I've printed multiple units, one for each room in my home. This is the third iteration which features screw-together design. Replacing batteries will now be a seamless process. The outer diameter measures 60 mm and the inner socket spans about 58 mm. It boasts an M58x1.5 thread, making it easy to assemble by simply screwing them together. At its core, the thermometer relies on an Espressif ESP32 and a Bosch BME280. This combination enables accurate measurement of Temperature, Humidity, Air Pressure, and Battery Voltage. All collected data is transmitted via MQTT to my Homeassistant setup. Below are the essential components: ESP32: Available at https://www.aliexpress.com/item/ESP32-ESP-32F-module-ESP32-Adapter-Board-WiFi-Bluetooth-low-power-dual-core-CPU-MCU-Internet/32843063740.html BME280: Obtainable at https://www.aliexpress.com/item/High-Accuracy-BME280-Digital-Sensor-Temperature-Humidity-Barometric-Pressure-Sensor-Module-GY-BME280-I2C-SPI-1/32672210336.html To complete the project, you'll need some resistors, capacitors, and a LiFePo4 Battery. I can provide a comprehensive parts list and my source code as open-source if anyone is interested.
