Case for 2-channel relay, NodeMCU, switch & BME280
Description
## Introduction A simple case to house a NodeMCU v3, a double 5v relay, a BME280 temperature and humidity sensor and a small switch. I use this case to make my boiler smart by replacing the connection to my thermostat with one of the relays, though it can of course by used in multiple different ways. The BME280 temperature and humidity sensor has a small compartment with ventilation holes, to prevent the heat from the NodeMCU and relay board influencing the readings too much. ### Notes The lid is a bit loose. This case is normally not moved in this situation that I am using this therefor this doesn't give any issues, but keep in mind when printing this. ## Materials used - [2-Channel 5v relay](https://aliexpress.com/item/32997387727.html) - [NodeMCU v3](https://aliexpress.com/item/32719926758.html) - [Push Button Switch](https://aliexpress.com/item/32840177333.html) - [BME280 3v Sensor](https://aliexpress.com/item/32862445164.html) - M5 * 8 mm hex nuts (though 4 / 6 mm should work as well) - Dupont / Jumper cables ## Software - [Overview on Github](https://github.com/MichielvanBeers/Smart-Boiler)
