Check temperature, humidity, dewpoint provided by a sht11 temperature and humidity sensor from 1 powered by an ATmega from 2 on a json web page. I bought and assembled this system in 2007 and it is still working!
{
"Sensor": {
"SensorID": "192.168.100.19",
"Temperatur": "25.7°C",
"Feuchtigkeit": "55%",
"Taupunkt": "15.0°C"
}
}
Example:
/usr/local/bin/check_json_temp.py -H <IP> -sensor 0 -w 30 -c 40 -temperature -humidity -dewpoint
OK: Temperature: 25.7 C|Temperature=25.7;30;40 Humidity=55.0 DewPoint=15.0
