So here we are now making one automatic smart exhaust fan controller system using Arduino UNO which will work for three bathrooms that are all connected to a single ventilation pipe and one common exhaust fan. This whole project is going to be based on PIR sensors for human detection, VOC sensors for odor detection […]

How to Use Diodes, Transistors, ICs as Temperature Sensors
Normally we find thermistors being used as the sensor for detecting and monitoring temperatures in electronic circuits. However, ordinary semiconductor components like transistors and diodes actually work better than thermitors when it comes to detecting temperature changes. In fact, this feature happens to be one of the greatest drawbacks of semiconductor devices, whose working characteristics […]
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 […]
Using TSOP17XX Sensors with Customized Frequencies
The TSOP17XX series ICs are special infrared sensor devices built for responding to specific range of infrared frequencies and convert it into an electrical pulsed output. It thus features a foolproof immunity to other forms of IR signals. Due to this specific center or band-pass operating frequency of a TSOP17XX, it becomes difficult to use […]
