Text herein is the continuation of my previous work with ESP8266-07 WiFi module. That work was related to connecting the ESP with humidity/temperature sensor (DHT22) and pressure sensor (BMP180). The weather station prototype described here consist of set of ready-to-use modules: ESP8266-07, DHT22, BMP180 and DC-DC converter module (built on LM2596HV chip). All components mentioned above was purchased in arduino-ua.com shop. As enclosure was used standard box with flanges from Gainta (model G203MF).
The described device includes the next sensors – DHT22 and BMP180 which allows to measure such parameters of an weather condition as temperature, humidity and pressure,
- Pressure 300…1100 hPa (30…110 kPa)
- Temperature -40…+80 °C
- Humidity 0…100%
Power supplies to this device with AC-DC adapter 220V-9v(5V), voltage from such adapter is additional converted with DC-DC converter to the level 3,3V.
