In this video, I'm making a carbon monoxide monitor for my home using an MQ7 carbon monoxide sensor, a DHT11 temperature and humidity sensor, and a NodeMCU microcontroller board. This sensor is ...

In our everyday lives, environmental conditions like temperature and humidity can have a big impact, whether it’s in your home, office, greenhouse, or server room. Imagine leaving your room for a few ...

DHT11 and DHT22 are two popular sensors among microcontroller users, especially the cheap DHT11s. DHT22s cost more but have better data resolution. My codes are based on MonadnockSystems/pxt-dht11 but ...

Abstract: Press-pack power module has recently become a crucial component for large-current and high-power facilities. Several semiconductor chips are connected in parallel inside the module. Due to ...

Tired of condensation wrecking your shed tools or greenhouse gear? I built a no-frills ESP32 + DHT22 node that wakes every 15 minutes, grabs temp/humidity data, beams it over Wi-Fi, and sleeps—running ...

Abstract: In recent years, Simultaneous Localization And Mapping (SLAM) technology has prevailed in a wide range of applications, such as autonomous driving, intelligent robots, Augmented Reality (AR) ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
