Raspberry Pico-W based thermometer and hygrometer

Raspberry Pi Pico W Hygrometer (Micropython)

Wifi-connected thermometer and hygrometer. Uses the DHT22 sensor and uploads data to thingspeak.com.

Operation

Measurement/Upload is done every 5 minutes. If no wifi is available the measured data will be lost. During the measurment the internal LED is on, inbetween measurement the LED pulses at ~1 Hz to signal a sign of life.

Usage

A file secrets.py must be created containing wifi network information (ssids/passwords) and API keys for the data upload.

Example for secrets.py

WIFI_KNOWN_NETWORKS = [
    {
        "ssid":">>>first-network-ssid<<<",
        "password":">>>first-network-password<<<"
    },
    {
        "ssid":">>>second-network-ssid<<<",
        "password":">>>second-network-password<<<"
    }
]

UPLOAD_WRITE_API_KEY = ">>>your-api-key<<<"
UPLOAD_READ_API_KEY =  ">>>your-api-key<<<"
