Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

To design and implement a smart home system that automates the control of lighting and fan speed based on environmental conditions. The project uses an ATmega32 microcontroller, LM35 temperature ...

General purpose circuit of the simple pressure sensor alarm is built around a couple of readily available cheap components. Working of this circuit is straight forward and self-explanatory. When the ...

ESP32 reads LDR sensor data and converts it to a percentage (1-100%). MQTT communication using the EMQX Cloud broker. Node-RED flow for real-time data visualization and analysis. Dynamic lighting ...

Thermistors are used as temperature sensors, for example, in fire alarms. Their resistance decreases as the temperature increases. At low temperatures, the resistance of a thermistor is high, and ...

When most of us think of glove controllers, the first which comes to mind is Nintendo’s PowerGlove, which promised much more than it delivered. But the idea persists, and from time to time we see them ...

Abstract: Solar panels can be used to convert solar energy, a renewable resource, into electrical energy. The quantity of solar radiation that solar panels receive affects how much electrical energy ...
