Temperature to period circuit provides linearization of thermistor response

Temperature-to-period circuit provides linearization of thermistor response

Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors’ resistance-versus-temperature characteristics are highly nonlinear and need correction for applications that require a linear response. Using a thermistor as a sensor, the simple circuit in Figure 1 provides a time period […]

Raspberry Pi controlled room temperature monitoring with Gnuplot image output and email alert ability

Raspberry Pi controlled room temperature monitoring with Gnuplot image output and email alert ability

Where I work, there is a very important room which houses lots of computers. The ambient temperature of this room has to be very cool to optimize performance of these systems. I was asked to come up with a monitoring system which has the ability to send some form of alert to a few people

Raspberry Pi Temperature Sensor

Raspberry Pi Temperature Sensor

A few weeks ago, I purchased a Raspberry Pi. After reading Eben Upton’s Raspberry Pi User Guide, particularly the two chapters on which he focuses attention on the GPIO, I had an idea for my first project. The post covers the first iteration of a home temperature monitoring project I put together using a Raspberry
