A PM-11z host can directly connect to 15 wireless sensors.With wireless repeaters, the number of sensors and network coverage can be expanded.Each wireless repeater can expand 15 additional sensors.The sensor can automatically measure according to the time interval set by the user and transfer the stored data to the PM-11z host regularly.

Features

·   Can meet the experimental requirements of most plant studies

· No wiring required, flexible measurement, large coverage

· The sensor is powered by a battery (3 AA batteries) and lasts for a long time (6 months or even longer)

· The host and repeater must be connected to external AC power or powered by solar panels

System composition

·   A variety of optional sensors are provided, and the probe is connected to the wireless signal transmitter through a shorter cable.The sensor can store 4096 sets of data and send it to the PM-11z host regularly.The sampling interval time can be set to 1, 5, 10, 15, 20, 30, 60, 120, 180, 360, 720 and 1440 min (1 d).Data can be collected for 4 weeks at a sampling frequency of 10 min.

·   Router wireless repeater, signal relay between the sensor and the PM-11z host.With multiple repeaters, the number of sensors and network coverage can be greatly expanded.Each repeater can expand 15 sensors.

·   The PM-11z host communicates with the entire network, stores the collected data, and downloads the data to the PC wirelessly.The PM-11z host can directly connect 15 sensors, and the data is stored in the built-in SD card.

·   The PC terminal receiver is connected to the PC via USB, and can establish a wireless connection between the PM-11z host and the PC.

· PC-specific program, which can set sampling frequency, data upload interval, data download, etc.
