Ana Yagudaev oct. 1, 2020 Hi Paul Is it practical to use the sacks of three sensors spaced 20 m apart laterally in the big warehouses? We have a warehouse 350' X 250' x 25 with 40 double-sided racks. We used 75 sensors to map it, alternating the staking every other rack. One rack, we used double staking: low and top of each end of the rack, and next rack we position the sensor in the geometrical middle of the rack. Also, we placed sensors on the racks affected by HVAC discharge. Do you consider it is acceptable? How many sensors will you think we will need to perform three-stack mapping? Reply
