This sensor will be used to analyze and address red tide pollution, a critical environmental issue driven by cyanobacteria and harmful algal blooms (HABs) affecting Japan’s coastal ecosystems.

Guwahati: Developed at an extremely low cost, using pencil, paper and graphene oxide, researchers at Gauhati University claim to have built high-tech sensors, which can help farmers check humidity ...

The SHT40-AD1P-R2 and SHT41-AD1P-R2 digital humidity and temperature sensors provide highly accurate measurements. The SHT40-AD1P-R2 offers ±1.8% RH (max. ±3.5%) and ±0.2°C, and the SHT41-AD1P-R2 ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “ DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to ...

Next, determine how damp the space is by using a hygrometer, a device that measures the relative humidity in a room. You can buy a digital hygrometer for as little as $10. Keep in mind that ...

8. How air temperature and pressure can affect indoor air quality In addition to VOCs, PM2.5, radon, carbon dioxide and humidity, Anna's air quality sensors also display air temperature and pressure.

Pope Francis is no longer using mechanical ventilation for help breathing at night and his doctors believe he will continue to improve, the Vatican said on Wednesday, in the latest positive update ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed Lookup Tables” was published by University Minnesota and Cadence. Abstract ...

We fabricated Plastic Optical Fiber (POF) humidity sensors using a humidity-swelling polymer as the cladding. This sensor changes from the leakage to waveguide mode at a certain humidity. The purpose ...

Renesas has recently released the RRH47000-EVK evaluation board based on the RRH47000 CO2 sensor using non-dispersive infrared (NDIR) technology to measure CO2 levels accurately (±75 ppm typical) ...

The ultrasonic sensor sends a pulse and measures the reflection time. The ATmega32 calculates the distance based on the reflection time. The LCD displays the distance in cm. LEDs and buzzer respond ...

Using magnets, rather than a direct point of contact, the Hall Effect allows thumbsticks to possess increased accuracy by reading electromagnetic waves, and eliminated stick drift as a possibility.
