Elecrow hit Kickstarter with an electronics learning lab-in-a-box based around the Raspberry Pi. A 2nd generation crammed the lab into a laptop form factor. The CrowPi 3 "playground for programming, ...

Smart wearables company Ultrahuman has launched a new device that monitors changes in home environments that could impact ...

This breakthrough technology integrates a highly sensitive humidity sensor with a thermistor and micro-heater, enabling exceptional accuracy in behavior recognition. By using porous nanoforests as ...

The Aqara Temperature and Humidity Sensor is a low-cost, simple, yet useful device that can enhance your HomeKit setup significantly. Here’s why you might want to install one in every room.

If you want to add humidity ... sensors to your home automation sensor, you can — like [Maker’s Fun Duck] did — buy some generic ones for about a buck. For a dollar, you get a little square ...

#define DHT_SENSOR_PIN 7 // value for pin connected to DHT11 sensor... #define DHT_SENSOR_TYPE DHT11 // value for sensor type... #define DEBUG true // set to true for console output, false for no ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Your smart speakers have more built-in functionality than you might have realized if you've just been using them to queue up playlists and get weather forecasts. Dig a bit deeper into their ...

Würth Elektronik has shrunk a humidity sensor into a 1.5 x 1.5 x 0.5mm 5pad DFN package. Called 2525020210002, it works over 0 – 100% relative humidity, typically to within ±1.8%RH (±3.5%RHmax) over ...

The circuit diagram of the coal mining safety robot is shown in Fig. 3. The circuit comprises an Arduino Uno board, Zigbee, temperature sensor, gas sensor, humidity sensor, relay, LCD, DC motor, ...
