Full wireless pressure/temperature/humidity sensor with radiation shield (BME280)
thingiverse
A new version of my weather station is being built here: https://www.thingiverse.com/thing:4120452 This wireless weather station measures temperature, humidity, and air pressure using a BME280 module for the sensor and an nrf24l01+ module for wireless transmission. The core controller is an atmega328p standalone device that can be programmed with arduino. You will need: - 4 M4x80 nuts and bolts for the top cup - 1 M4 nut for the base - 5 little screws, 2.9x6.5 or 2.9x9.5 The schematics and pcb pictures are included in a zipfile. Openscad source code is also provided, but you will need to check if any variable values have changed. A radiation shield can be printed with ASA (acrylonitrile styrène acrylate), which is a UV-resistant material. Solar cell power information is available here: https://www.thingiverse.com/thing:3593223 More details are on this blog post: https://blog.zesanglier.fr/2019/02/02/station-meteo-capteur-de-temperature-humidite-et-pression-bme280/
