Highlighting projects we’re working on and gadgets we’ve built.

Water depth sensor display

We have several dozen pressure transducers deployed in wells or in streams to measure water level, and sometimes it’s helpful to read the water level directly from the sensor.  This model of sensor has an analog output, meaning that the circuitry supplies 5 volts DC to one wire, and the voltage on the return signal wire is proportional to the depth of the water.  So by measuring the analog r...[Read More]

Clear enclosure dataloggers

We have had a number of Arduino dataloggers deployed for a couple years now.  The first ones were based on the Arduino Pro boards and a datalogger shield from Adafruit.  Our newest version is based on the Seeeduino Stalker board.  It’s handy because it has a built-in real time clock (RTC), solar charging circuitry, a microSD memory card slot, and an XBee radio socket.  On top of the Stalker ...[Read More]
