Wireless Plant Physiological and Ecological Monitoring System - PM-11z

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

characteristic

·Can meet the experimental requirements of most plant research

·No wiring required, flexible measurement, wide coverage area

·The sensor is powered by batteries (3 AA batteries) and has a long continuous working time (6 months or even longer)

·The host and repeater require external AC power or power supply from solar panels

system composition

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

·Router wireless repeater, which relays signals between sensors and PM-11z hosts. By using multiple repeaters, the number of sensors and network coverage can be significantly expanded. Each repeater can expand up to 15 sensors.

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

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

·PC specific program that can set sampling frequency, data upload interval, and data download, etc.
