Multi-channel wireless environmental temperature and humidity meter, parent and child unit set AD-5664SET 1 unit

[Applications] For agricultural greenhouses. For measuring temperature and humidity and soil temperature (ground temperature) inside greenhouses such as rice seedling greenhouses, and for warehouses for vegetables, fruits, and alcohol. For temperature and humidity control of crops such as vegetables and fruits, fermentation and brewing of sake breweries and wine, and for temperature and humidity control of factories, offices, gymnasiums, facilities, and homes, and for managing the risk of heat stroke and influenza epidemics. 【Features】 Wirelessly displays temperature, humidity, heat stroke index (WBGT), and absolute humidity (VH) from remote locations. It can be used to learn about the risk of heatstroke and seasonal influenza epidemics. Up to five child units can be connected to one parent unit. The communication distance is up to 100m (line of sight, height 1.2m). Built-in sensors measure environmental temperature and humidity. Temperature probes (sold separately) can be connected, up to two can be connected to one sub-unit. Can measure soil temperature and liquid temperature (temperature probe cable length approximately 2.5m). The handset also has an LCD display, so you can check the measurement values ​​at the measurement site. Specific low-power device, radio frequency is 429.2MHz.
