Random spikes with AM2302 Temperature & Humidity sensor

I built for logging auditing purposes a simple Temperature & Humidity datalogger, using an DS18B20 temp sensor for sensing an equipment rack and a AM2302 (also know as DHT22) Temperature & Humidity sensor for registering the ambient temperature inside the room. This setup is running 24 hours a day r...

Paer: Low-cost plenoptic camera with off-the-shelf componentsp

Abstract: We present a proof-of-concept for plenoptic imaging on a low-power Raspberry Pi 3B platform at low hardware cost. The light field is sampled by a 4 by 4 array of 5 Mpixels cameras connected with stackable multiplexer modules in order to avoid the need for one Raspberry Pi per camera. Impl...
