In this post I have explained the working of 3 interesting and useful temperature alarm circuits through detailed circuit diagrams. A temperature alarm circuit is basically a device which is designed to detect a temperature threshold and sound an alarm as soon the temperature exceeds over, or drops below the desired temperature detection threshold. 1) […]

Temperature Controlled DC Fan Circuits
Have you ever turned up your amplifier all the way, either at a party or just for fun? You may have noticed that “it gets hot” and thought that a fan would be useful. However, at low listening levels, you can hear the fan running. With this circuit, the fan will be automatically controlled by […]
Contactless Sensors – Infrared, Temperature/Humidity, Capacitive, Light
In this article I have explained a few highly advanced contactles sensors such as infrared sensor, temperature sensor, humidity sensor, light sensor which can be used for crucial and sensitive industrial applications, and manufacturing plants. Texas Instruments (TI) introduced the growth of its industry-leading sensing integrated circuits with the inclusion of 4 innovative products that […]
Interfacing DHTxx Temperature Humidity Sensor with Arduino
In this article we are going to take a look at DHTxx series sensors, which is used for measuring temperature and humidity, both the functionality is integrated into one module. We are going to see their specification, so that you can choose best sensor for your project and finally we are going to interface it […]
4 LED Temperature Indicator Circuit
The 4 LED temperature indicator circuit discussed here is very useful for getting a visual information regarding the state of temperature which is to be monitored. Circuit Operation In the circuit temperature status is displayed using four LEDs. – A green LED, indicating that the temperature is in the desirable level- Two yellow LEDs are […]
Temperature Controller Circuit for Reptile Racks
The following article discusses a temperature controller circuit which can be used for controlling the temperature inside reptile racks. The idea was requested by Mr. Tom. Technical Specifications I’m looking to make a circuit to use to heat my reptile rack, I really like your incubator circuit, but do not have the electronics expertise to change it to suit […]
