QTR-HD-31RC hub-lorawan status/heartbeat

status/heartbeat

PWML is pulled high and PWMH is pulled low internally

providing reliable long-range detection ranges

The GP2Y0A21 uses a 3-pin JST connector that works with our 3-pin JST cables for Sharp distance sensors (not included) as shown in the upper picture on the right

Target detection: ~4 s acquisition time / ~5 s release time

QTR-HD-31RC hub-lorawan status/heartbeatThis array of IR LED phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage and separate controls for the odd and even emitters. In general, the closer the object, the higher the contrast between light and dark readings, but high reflectance objects are generally detectable out to around 50mm.
