Liquid Level Switches | Optical Liquid Level Switches ...

SST Sensing’s optical liquid level switches are solid state, so there are no unreliable moving parts. They are compact, only protrude a small distance into the application and are able to detect small amounts of liquid.. The intelligent liquid level sensors have low sensitivity to ambient light and are not affected by foam when in air, or small bubbles when in liquid.

Overview | Adafruit SCD-30 - NDIR CO2 Temperature and ...

Jan 06, 2021· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Oxygen sensor - Wikipedia

An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed.. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ...
