A hall effect sensor mounted to the door frame tells me what angle the door is opened to. When I plotted output over angle, my data wasn’t exactly linear but good enough for an electric door opener.

In quantities of 1,000 units, the TSL2014 linear sensor array costs $35.39 each and the TSL210, $27.48. TEXAS ADVANCED OPTOELECTRONIC SOLUTIONS INC., Plano, TX. (972) 673-0759.

To adapt the demands of the high-speed and real-time dynamic measurements, a linear array sensor (LAS) and projection fringe-based vision system was proposed to measure the radial vibration of ...

A current mirror was used as a conditioning circuit for each FSR sensor (Esposito et al., 2019a, b).It was made of a pair of common npn BJT (2N2222), positioned very close to each other. Basically, ...

Differential line arrays (DLAs) hold significant potential for practical signal enhancement, but DLAs are not capable of realizing the Nth-order fully steerable function. To overcome this problem, ...
