How to lower relay power consumption
https://www.electronics-lab.com/lower-relay-power-consumption/
Clever way of starting-up relays discussed in this app note from Maxim Integrated. via dangerousprototypes.com Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a relay coil may be unattractive for battery-operated applications. You can lower […]
Arduino OLED Hygrometer and Thermometer using DHT11
https://www.electronics-lab.com/arduino-oled-hygrometer-thermometer-using-dht11/
Hygrometers are used to determine the moisture content of the environment. They find application in farms, food storage, museums, and other places where moisture needs to be monitored to ensure damage is not done to goods and other things stored in that space. For today’s tutorial, we are going to build a Hygrometer using the […]
Chemical sensor monitors sewage waste waters to expose polluters
https://www.electronics-lab.com/chemical-sensor-monitors-sewage-waste-waters-expose-polluters/
A new sensor system developed by Fraunhofer researchers and their partners could help safety agencies identify wrongdoers who covertly discharge hazardous wastewater into sewers to avoid specific disposal costs. By and large, safety agencies currently have no means of detecting this kind of environmental crime on a broad scale. But this illegal sewage poses major […]

Amplifier Classes
https://www.electronics-lab.com/article/amplifier-classes/
Introduction Amplifiers are commonly classified depending on the structure of the output stage. Indeed, the power amplification really happens during that stage and therefore the quality and efficiency of the output signal is dictated by the architecture of the amplifier’s output. The classification consists of an alphabetical arrangement A, B, AB and C that relates […]

Energy-efficient power electronics – gallium oxide power transistors with record values
https://www.electronics-lab.com/energy-efficient-power-electronics-gallium-oxide-power-transistors-record-values/
The Ferdinand Braun Institute for Highest Frequency Technology (FBH) in Berlin has achieved a breakthrough with transistors based on gallium oxide (ß-Ga2O3). The ß-Ga2O3 gallium oxide MOSFETs developed by FBH scientists provide a high breakdown voltage with high current conductivity. With a breakdown voltage of 1.8KV and a record power density of 155 megawatts per […]
