This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with ...

The sensor at address 000 is at room temperature, the sensor at address 001 is at a low temperature, and the sensor at address 010 is at a high temperature. When you select no external sensor, the ...

The circuit is very simple — a one-transistor Colpitts oscillator with no power amplifier, and thus very limited range.

A very simple temperature indicator can be built around an 8-bit RISC microcontroller (see the figure). Data from a temperature sensor is processed by the MCU and used to display ...

The circuit, including the indicatingmeter, can fit into a small housing,such as an empty 20g glue-sticktube. An ordinary 1N4148 silicon signaldiode serves as the temperature sensor,exhibiting ...

Of course, we know better. Inside his gadget is a simple temperature sensor, an ATtiny841, a very nice home-made PCB, a buzzer, an LCD, and some pushbuttons.

With an ESP32 and a simple sensor, I can slap my table to turn on my PC for less than $5.

Latest to store shelves is Elgato 's Eve Degree, a compact temperature, humidity, and air pressure sensor, wrapped up in a simple and handsome design, and promising to be the smart trigger your ...

The plug-in sensor package they've developed monitors multiple phenomena in a room, including things such as sounds, vibration, light, heat, electromagnetic noise and temperature.
