Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

This design makes it an appealing choice for people with aquariums, hydroponic farms, or any other situation where constant monitoring of pH is extremely important to maintaining a balanced system.

The pH sensor is calibrated outside the bioreactor using buffers at pH 4 and pH 7 (left). The sensor is then built into the bioreactor and sterilized by autoclaving (middle).

Chemists develop new sensor for microvolume pH detection by Xi'an jiaotong-Liverpool University A The schematic drawing of the as-prepared microfluidic solid-state pH sensor.

A graduate student at Southern Methodist University (SMU), has developed a miniature pH sensor that can detect when food has spoiled in real-time.
