Since I wrote About1 I have purchase several more Raspberry Pi computers. I had 3 model Zero - WH until one day I connected the ground pin to a 5 volt power pin. After that I had a fried Pi.
Prior to the Fried Pi I had one installed in the master bedroom with the BME280 Humidity, Pressure and Temperature sensor, one in the dining room with the same kind of sensor and the third out doors connected to the sensor as well as being connected to a wind annometer(measures wind speed), a wind vane (measured wind direction) and a rain guage.
These 3 computers all have Wifi installed so they sent the data from the sensors to a Raspberry model 4. (See below)
The Raspberry 4.
This computer has 8 gb ram installed and is connected to a 1 TB external hard drive. The operating system (OS) is installed on a 64mb USB memory stick. The code for this web site is stored on the hard drive as well as the PostgreSQL database.
