Overview & Working Principle
Our wireless pressure solution combines a sensing front-end (e.g., WPCK05/07/62 transmitters or WPAK MEMS cores) with a low-power radio node and industrial enclosure. Data is sent at defined intervals to a network (LoRaWAN gateway or cellular NB-IoT/LTE-M), then to your platform via MQTT/HTTP or into a BMS/SCADA.
