PNI MS500 Wireless Weather Station – Digital Indoor/Outdoor Climate Monitor with Backlit LCD, 433 MHz Remote Sensor, Comfort Indicators & Ventilation Recommendations

The PNI MS500 wireless weather station is a commercial-grade environmental monitoring system precision-engineered to deliver comprehensive, real-time climate data for commercial buildings, residential complexes, and managed storage spaces. Utilizing advanced 433 MHz radio frequency technology, the primary console establishes a high-stability wireless link with its remote outdoor transmitter to capture accurate meteorological metrics up to a maximum open-field distance of 50 meters. It serves as an essential logistics procurement component for facility management offices, indoor botany hubs, warehouse climate controllers, and high-volume B2B consumer electronics and radiocommunication hardware wholesale distribution networks looking to stock robust environmental tracking gear.

The system features an intelligent, multi-channel architecture outfitted with 3 communication channels that support the simultaneous pairing of up to three independent outdoor transmitters. When multiple sensors are active, the system allows operators to cycle through channels manually or activate an automated 10-second loop display. To ensure seamless operation out of the box, the included remote sensor arrives pre-paired from the factory. Engineered with an IPX4 water-resistance rating, the external probe safely withstands atmospheric water spray and rain, tracking extreme outdoor thermal environments spanning from -40°C up to +60°C with a tight 0.1°C resolution profile.

	Weather station with outdoor sensor The PNI MS500 weather station offers detailed information on weather conditions both inside and outside the house. PNI MS500 adopts RF technology to communicate quickly and stably with the outdoor sensor that obtains accurate temperature and humidity data and transmits it at a maximum distance of 50 meters to the house weather station. The weather station has 3 communication channels and supports the simultaneous pairing of 3 outdoor sensors. In this situation, the display of the external temperature on the weather station screen is done by selecting one of the 3 channels in turn or cyclically (it shows the 3 channels in the loop, in an interval of 10 seconds). The sensor included in the weather station package is factory paired.
Thermal indicators for interior and exterior. The large, backlit display can show all important data such as temperature, humidity, weather or recommendations for changing indoor environmental conditions at a glance. The screen is efficiently divided in two, to display environmental data both indoors and outdoors simultaneously.
	Detailed weather values The weather station accurately displays the temperature in the range of -9.9 ° C ~ + 50 ° C and the humidity in the range of 20% ~ 95% RH. If the temperature exceeds this range, the “low” and “high” warning symbols will be displayed on the screen. In addition, through the thermal comfort indicators (WET-Wet, COMFORT-optimal and DRY-dry) you will always enjoy a pleasant and comfortable life.
Memory of minimum and maximum measured values The weather station automatically saves the minimum and maximum values recorded both indoors and outdoors. The measured minimum and maximum values can be stored in memory for 24 hours (meaning they will be erased every day at night) or they can remain in memory until the battery is replaced.

The central console is optimized for indoor desks or wall mountings, featuring a split-screen backlit LCD display that shows concurrent indoor and outdoor telemetry data at a glance. For advanced indoor atmospheric control, the PNI MS500 generates automated weather forecasts and environmental ventilation recommendations based on dynamic relative humidity metrics ranging from 20% to 95% RH. Powered by standard AAA batteries, this turnkey instrumentation package ensures immediate environmental alignment, tool-free field setup, and absolute multi-shift deployment readiness.
