Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

In each beaker, a pH sensor (Atlas Scientific, Long Island City, NY, Gen3 pH sensor, resolution 0.001 pH) was placed and sampled at 1 Hz by an Arduino connected via USB to a Windows 11 PC. For the ...

These reporting molecules were linked to genetic circuits that detect nearby bacteria, but this approach could also be combined with any existing sensor, such as those for arsenic or other ...

For each bacterium, the researchers engineered the enzymes necessary to produce the reporter into the host cell, then linked them to genetically engineered sensor circuits.

The University of Glasgow has created a pH sensor for soil testing that can be composted at the end of its life. It is an impedance-based sensor, using screen-printed interdigitated carbon-based ...
