Solar Powered Temperature Sensors

Solar-powered temperature sensors use photovoltaic panels to charge internal batteries, supplying stable 12 VDC power to the sensor electronics. OSI's instruments require a nominal maximum of 400 mA, making them highly efficient for solar operation. They transmit data via RS-232, RS-485, Ethernet, or optional cellular modems, enabling real-time monitoring from any location.

OSI's solar-compatible sensors are rated for operating temperatures from -50°C to 60°C (-58°F to 140°F), making them suitable for extreme environments ranging from polar Antarctic conditions to tropical rain forests. Integrated dual self-regulating lens heaters provide additional protection against frost, dew, and snow buildup in cold climates.

No. OSI's DSP-based sensors require no field calibration. Advanced environmentally adaptive algorithms with automatic compensation for dust, water droplets, and ice on optics ensure sustained accuracy throughout the sensor's operational life — significantly reducing total cost of ownership for remote solar-powered installations.

OSI's sensors are ISO 9001:2015 certified and CE certified. Select models meet FAA AWOS present weather requirements and comply with NWS and WMO weather code standards. These certifications make them suitable for use in regulated environments including airports, state DOT road weather systems, and government meteorological networks.

Yes. OSI's modular weather stations, such as the OWI-432 WIVIS and MAWOS, support easy integration with additional sensors and third-party systems. Communication interfaces include RS-232, RS-485, Ethernet, MODBUS RTU, and optional spread spectrum radio, satellite, GSM, and cellular modems for seamless compatibility with existing infrastructure.

Solar-powered temperature and weather sensors are widely used in aviation, highway transportation, environmental research, marine and ocean monitoring, military operations, solar and wind energy farms, railway safety systems, and emergency response. OSI's instruments serve customers including NASA, the FAA, NOAA, the EPA, state DOTs, and national laboratories across the globe.
