Temperature and Humidity of CCTV DVR as Monitored by a Raspberry Pi.

Estimate the signal strength in a bandwidth around a center frequency using an RTL-SDR radio attached to a Raspberry Pi 2 and Communications System Toolbox Support Package for RTL-SDR Radio and Simulink Support Package for Raspberry Pi.

Using a raspberry pi b+ GPIO pins and python I constructed a 15 sec updating feed from a DHT22 humidity sensor, and two DB20S18 temperature sensors to give an outside temperature and humidity and inside temperature every 15 seconds to Thingspeak

I am currently setting up my Raspberry Pi 2. While doing so, I am enabling upload of some, more or less, important parameters, showing status of the device.
