PCR2-IN Datasheet


PCR2 are bi-directional people counters that use a novel 24 GHz radar transceiver to detect motion from both directions simultaneously. This allows the devices to be mounted parallel to the walking direction. PCR2 detects both directions independently when a certain distance exists between people. Meter readings are transmitted at regular intervals over a public or private LoRaWAN™ network. All parametric sensors are equipped with a USB configuration port for firmware setup and update.

Mounting Options

Wall mounted

When mounted at a wall PCR2 can detect people passing by in both directions on walkways 0.5m up to 5m wide.

IMPORTANT: Persons walking side-by-side will be counted as one person.

Wall mounting

Ceiling mounted

When mounted over head take care that there is more than 50cm distance between persons head an the sensor

IMPORTANT: Persons passing by walking side by side ca not be separated and will be counted as one person.
