Electronic Ballast Circuit for UV Germicidal Lamps
In this post I have explained the construction of a DC UV germicidal lamp ballast circuit which can be used for driving any standard 20 watt UV lamp through a 12 V DC source. Although, the proposed ballast design was originally meant for illuminating a regular 20 watt fluorescent tube light, this can be also […]
Ultrasonic Hand Sanitizer Circuit
The ultrasonic hand sanitizer circuit detects the presence of human hand through reflected ultrasonic waves, and triggers a relay solenoid pump momentarily for dispensing the sanitizing liquid on the hands of the user. The project uses the popular HC-SR04 ultrasonic sensor module for the required sensing function. Using HC-SR04 The HC-SR04 ultrasonic sensor module is […]
Face Mask with UVC Disinfected Fresh Air
Face masks have so far proved to be the most effective first line of defense against all contagious epidemics and pandemics. However, the biggest discomfort with face masks is the difficulty in breathing and accessing fresh air. On the other hand, if the masks are made porous for letting fresh air in could also allowing […]
Digital Thermometer Circuit – Uses a Solar Cell for Power
The articles explains a digital thermometer circuit project that works without a battery. Instead of a battery the circuit utilizes a small solar cell and operates by deriving power from the ambient light available from the surrounding light sources. This allows the circuit to be extremely compact, light weight, versatile and hassle free while measuring […]
