Air Temperature

Air Temperature

The Harvest Air Temperature Sensor is fully designed and manufactured in house, calibrated in an ice water bath and has an accuracy of ±0.1°C. It has a usable temperature range of -55 to 125°C (-67°F to +257°F) and uses the Dallas 1-Wire interface.

The white solar radiation shields around the sensor are also designed by Harvest to protect the sensor from the effects of the sun while maintaining air flow.

Combined Temperature/Humidity/Pressure

Combined Temperature/Humidity/Pressure

The Harvest Air Temperature/Relative Humidity/Barometric Pressure Sensor is designed and built in house. The sensor has a calibrated accuracy of ±0.1°C (temperature), ±1.5% relative humidity, and ±1.5mbar barometric pressure. 

The white solar radiation shield around the sensor is designed by Harvest to protect the sensor from the effects of the sun while maintaining air flow.

Multi-Use Temperature

Multi-Use Temperature

The Multi-Use Temperature Sensor uses a digital sensor with long term stability without requiring recalibration. The sensor is housed in a waterproof stainless steel enclosure and has a usable temperature range of of -55 to 125°C (-67°F to +257°F). Each sensor is calibrated at Harvest in an ice bath to 0.1C accuracy.

Ecowitt Ultrasonic Wind + THP Sensor

Ecowitt Ultrasonic Wind + THP Sensor

The Ecowitt features ultrasonic wind speed and direction measurement, capable of recording up to 40m/s (144km/h, 89mph) along with air temperature, relative humidity and barometric pressure. It boasts long-term stability of ultrasonic wind readings at an affordable price point (no mechanical wear and tear - calibration will not drift), with low power draw - making it compatible with all current generation Harvest devices equipped with an SDI-12 port.
