Apparatus for counting objects is disclosed. Apparatus includes a power source (), a radio transceiver (), two or more passive infrared (PIR) sensors (A,B,C), one or more memories () including computer program code (), a processor () to execute the computer program code (), and a mechanical field of view limiting structure (A,A,A,B,B,B,C,C,C) configured to limit the field of view of each infrared-sensitive element. The apparatus is caused to: detecting (), by the first PIR sensor, a first motion; detecting (), by the second PIR sensor, a second motion; if the second motion is detected within a predetermined time period after the first motion, increasing an inward count, or if the first motion is detected within a predetermined time period after the second motion, increasing an outward count; and transmitting the inward/outward count.

Apparatus for counting objects

Method for transmitting payload data in an electric power supply connector between a power source and a wireless apparatus is disclosed. Method includes: obtaining, by the power source, payload data to be transmitted; encoding, by the power source, the payload data using a predefined voltage modulation method; altering, by the power source, a voltage level of the electric connector in order to trigger the wireless apparatus to sample the electric connector; modulating, by the power source, the voltage level of the electric connector in order to transmit the encoded payload data to the wireless apparatus; and after detecting, by the wireless apparatus, that the voltage level of the electric connector is altered, starting, by the wireless apparatus, to sample the voltage of the electric connector in order to receive the encoded payload data, and decode the encoded payload data.
