Feb 2016: Why you need an analog front end and how to set...

Article February 2016, Why you need an analog front end and how to set it up. I'm trying to build the circuit shown in figure 7 of the article, but I have a few questions. 1. Should the LM356 be driven with a 5.0V supply, or 3.3V. 2. How should the -Rg (pin 1), +Rg (pin 8), and Ref (pin 5) on the AD...

Re: Build a PIC-Based Remote Temp Sensor

Today I finished the remote temperature sensor project. I don't have an Arduino, so I hooked up the output of the receiver to a PC serial port by using a MAX232 in the middle. Then I wrote a quick C# app to read the data and display the results. A few notes for anyone out there who is going to build...

Re: Build a PIC-Based Remote Temp Sensor

Nice article. I'm currently working my way through the project. So far I have only implemented the transmitter portion of the circuit, but I believe there is a problem with the checksum calculation. When you watch the data sent from the transmitter with a logic analyzer, the checksum never changes, ...
