We are rolling out our newest Wind & Solar Power Datalogger. A shunt between the battery and the power sources (wind turbines, solar panels, microhydro, your cousin on the exercycle), tell us the current being generated, and a voltage divider
Today I got a package from Sparkfun that included a Raspberry Pi 2, a couple of MOSFETS, some right angled breakaway headers, and a Proto Screw Shield kit. This shield makes it very easy to connect sensors to the Arduino,
I’m playing with a new wifi module today from WizNet, the WizFi210. I have mine mounted on a test board that has 9 pin rs-232, usb, and TTL Serial interfaces. There is an Arduino shield available as well. This is
We are investigating adding APRS abilities to our DIY Weather Stations. Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time tactical digital communications of information of immediate value in the local area. In addition, all such
We were asked to do a tutorial explaining how to do logging with the DHT22 Temperature Humidity Sensor. This is a little tricky, as the sensor outputs floats, and we send strings to the SD card, I’ve put together a
This tutorial will help you get the IC Station Micro SD Card Module up and running. This is ideal for recording data from sensors for future analysis. This is a 5v piece, where commonly sd card modules are 3.3v. The
