I am trying to put together a compact temperature control instrument to be placed inside a small chamber. For this I would like to buy a PID regulator, preferably with a sensor (Pt100) input and a relay output to switch a battery on/off. The difficult part is that I only have a volume of about...
I need to fit a WLAN transmitter into a tube, with inner diameter of 27mm or just over one inch, to transmit a lot of sensor data to a stand-by computer. The performance does not necessarily need to be stellar, 10Mbit or higher, and I can build my own circuit board to connect a set of chips...
My problem is to measure the water depth of ocean water, but only when the battery operated sensor unit is submerged. The sensor unit must operate on very little power and autonomously so I don't have information about when it is submerged, splashed on, or when it only reacts to barometric...
I am searching for a material that can fill the space between circuit boards carrying sensors and electroncs. I need to control the thermal gradients, both in space and time, between the various sensors and their electronics. Hence, the material must be electrically insulating. Another major...
