In MICRORISC, we have many sensors placed in the house and in warehouses, and the entire site is covered by the IQRF signal using only 1 repeater. You can watch a sample of the measurement in the video.
We are interested not only in warehouses but also offices. The measurement takes place in a two-story building, which has warehouses on the ground floor, where a suitable stable temperature of around 22-23 °C is maintained.
In south-facing rooms, temperature changes are more pronounced during the day. In the operations department or dining room, the evening temperatures rise to 25 °C due to sunlight, after sunset, the room gradually cools down, the minimum occurs before dawn.
The indoor pool measures the current values of temperature and humidity from the pool, rest area, or restaurant (measured with the basic sensor Industrial), and with the sensor Industrial X we measure the current values of water in swimming and children's pool.
Despite the demanding environment with a number of strong reinforced concrete walls and ceilings, the signal passed from the ground floor to the second floor without any problems using one repeater.
