Exterior Temperature Sensor – Solar Harvesting
Exterior temperature sensors with solar harvesting are designed to measure outdoor ambient temperature without requiring wired power or routine battery replacement. These sensors are commonly used in building automation, HVAC control, and energy management systems where reliable outdoor temperature data is required with minimal maintenance.
The 02LINE 10020076 sensor measures outside air temperature and transmits the value wirelessly to a matched receiver. Power is supplied by an integrated solar cell, making the device maintenance-free under normal operating conditions.
Sensor Operation and Data Transmission
The sensor continuously monitors ambient temperature and transmits updates based on defined change and time-based criteria. When the measured temperature changes by more than ±1 °C, the sensor immediately sends an updated value to the receiver.
To ensure data freshness even when conditions are stable, the sensor also retransmits the current temperature value at regular intervals of approximately 15 minutes. This periodic transmission allows receiving systems to confirm communication integrity and current readings.
Installation and Usage Considerations
Because the sensor relies on solar harvesting, it should be installed in a location with adequate exposure to ambient light. Placement should also consider protection from direct heat sources, reflective surfaces, or localized airflow that could distort temperature measurements.
Prior to commissioning, the operating manual should be reviewed to confirm mounting guidelines, wireless pairing procedures, and environmental limitations.
Frequently Asked Questions (FAQ)
What does solar harvesting mean for a temperature sensor?
Solar harvesting means the sensor is powered by an integrated solar cell, eliminating the need for external
power wiring or routine battery replacement under normal lighting conditions.
How often does the sensor transmit temperature data?
The sensor transmits immediately when the temperature changes by more than ±1 °C and also sends a
periodic update approximately every 15 minutes.
Is the sensor maintenance-free?
Under normal operating conditions and proper installation, the solar-powered design allows for
maintenance-free operation.
Where should an exterior temperature sensor be installed?
The sensor should be mounted outdoors with adequate light exposure while avoiding direct heat sources,
reflective surfaces, or airflow that could affect measurement accuracy.
