The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. It is therefore a challenge that today ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Arduino library for the ENS21x temperature & humidity sensor family with I2C interface from ScioSense. The ENS21x is a family of high-performance digital temperature and humidity sensors produced by ...

Abstract: Realization of a simple integrated and low-cost intensity modulation/direct detection-based humidity and vapor detection system utilizing zinc oxide (ZnO) nanorods as the active material is ...

Abstract: In this work an off-the-shelf, modern, integrated temperature, pressure and humidity sensor was interfaced to a PIC18F4550, a popular 8-bit microcontroller. A bit-banging SPI protocol was ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

When it comes to taking care of your home, you have a lot to think about, especially in the bathroom. While it is easy to think of the decor and fixtures, it is even easier to overlook one other ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
