SPARKFUN SST LIQUID LEVEL SENSOR
SPARKFUN SST LIQUID LEVEL SENSOR
The SST Liquid Level Sensor provides single point liquid detection via a TTL compatible push/pull output.
This optical liquid level sensor features a miniature design that allows for installation in areas where space is
limited. Thanks to its minimal solid state design, this sensor has been built without moving or mechanical parts
that can be jammed and stop working.
An infra-red LED and phototransistor accurately positioned at the base of the sensing tip ensure good optical
coupling between the two when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red
light escapes from the cone, causing a change in the amount of light present at the phototransistor, which
makes the output change state.
Features:
- Supply Voltage: +4.5 Vdc to +15.4Vdc
- Output Current: 100mA
- Temperature Range: -25 to +80⁰C
- Polysulphone Housing Tip
- M12 threaded connector (mounted from outside)
