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 ...
How Does the ESP32 WhatsApp Alert Message Work? The ESP32 uses its built-in WiFi to communicate with CircuitDigest Cloud WhatsApp API and send WhatsApp notifications whenever a sensor condition is ...
Every ham radio shack needs a clock; ideally one with operator-friendly features like multiple time zones and more. [cburns42 ...
3D printing has had its time to spread its wings into the everyday home, yet many of those homes lack the proper ventilation to prevent the toxic VOCs from escaping. Because of this, [Clura] has put ...
Abstract: This work demonstrates a deep learning–assisted microbottle resonator (MBR) humidity sensor coated with agarose and coupled to a tapered fiber. The convolutional neural network (CNN) ...
Abstract: This article presents a humidity sensor based on a micro-porous metal-organic framework (MOF) KAUST-7. A series of sensing-test experiments were performed and the results demonstrated that ...
Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost ...
