Analog pH sensors output a small analog voltage signal, generally in the millivolt range, that corresponds linearly to the pH value. This voltage signal is continuous and varies smoothly as the pH ...

If you're building up your smart home setup, introducing door sensors can be great for security, but they can bring a lot ...

We report a highly sensitive electrochemical sensor for the detection of Hg2+ ions in aqueous solution by using a thymine (T)-rich, mercury-specific oligonucleotide (MSO) probe and gold nanoparticles ...

Remote-sensing data and artificial intelligence are mapping the most heat-vulnerable buildings in cities like Delhi, in an ...

Since the 1960s, levodopa (LDA) has been the standard drug for treating of Parkinson’s disease. In this study, a novel benzothiadiazole-based conjugated microporous polymer-coated graphene ...

The system reads temperature, humidity, and soil moisture levels, displays the data on an LCD, and activates a water pump when the soil moisture falls below a specified threshold. arduino app hardware ...

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF ...

The sensor exhibits an ultrafast response and recovery time of approximately 180 ms, along with good repeatability. In addition, the sensor achieves a high sensitivity of 10.3 μA/% relative humidity, ...

This article presents a novel method for measuring the mass flow rate of gas-liquid two-phase flow based on the multi-sensor data fusion and soft computing model. A multi-sensor system comprising a ...

The E-Tongue is an easy-to-use device that tests for potential lead contamination in drinking water at home. Credit: Adapted from ACS Omega 2025, DOI: 10.1021/acsomega.5c01580 ...
