In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...
Abstract: A calcium alginate (CaAlg)-coated D-shaped single mode fiber humidity sensor is proposed in this paper. The sensor is fabricated by grinding single mode fiber and wrapping CaAlg with rolling ...
Abstract: While conventional optical fiber humidity sensors offer high sensitivity and stability, their size limits their application in narrow spaces. To overcome the limitation, this paper presents ...
