A simple and compact sensor based on a cascaded fiber Bragg grating (FBG)/droplet-like fiber structure is proposed for simultaneous measurement of refractive index (RI) and temperature. The sensor can ...

This circuit diagram illustrates a fire and smoke detection system using an Arduino UNO R4 WiFi, MQ2 smoke sensor, and a flame sensor (fire sensor). The Arduino is the central controller that receives ...

Want instant SMS alerts from your ESP32 without relying on a bulky GSM module?Whether it's motion detection, a sudden temperature spike, or an unauthorized locker door opening, your ESP32 can now send ...

This paper explains a design of spatial temperature measurement using some sensors that were connected using a small network. The sensors were intended to be placed on the ground and few meters below ...

The glass transition temperature (Tg) is an important physical parameter and signifies the reversible transition process between the glassy state and the rubbery state in polymeric materials. Herein, ...
