Computer aspirators with temperature and humidity sensors

Wadsworth’s temperature and humidity sensors provide accurate greenhouse readings. Sensors are inside a protective module which prevents direct sunlight exposure. The aspirated unit uses a fan to draw the air through, providing an actual ambient temperature reading, rather than radiant temperature. All Wadsworth computerized controls include an aspirated temperature & humidity sensor, and 100′ of shielded cable. There is no added charge. You can add aspirated temperature or temperature and humidity sensors to gather microclimate data in large zones.

Computer aspirator with temperature sensor only

Wadsworth’s temperature sensor provide accurate greenhouse temperature readings. Sensors are inside a protective module which prevents direct sunlight exposure. The aspirated unit uses a fan to draw the air through, providing an actual ambient temperature reading, rather than radiant temperature.

CO2 sensor

Wadsworth’s CO2 sensor uses non-dispersive infrared (NDIR) technology to measure CO2 concentration in the greenhouse air. Its microprocessor based electronics require less frequent recalibration than most CO2 units.

Soil temperature probe

For reading soil temperature, Wadsworth packages its proven semiconductor sensing element in a stainless steel tube that provides for fast, accurate readings while protecting the sensor.

Hot water sensor

Wadsworth packages its proven semiconductor temperature sensor technology in thermowells for insertion into hot water heating pipes, and in compact rapid response modules for mounting directly on the surface of heating pipes. Extended temperature range versions are available on special order if your application uses water warmer than 180ºF/80ºC.

Light sensor

(Pyranometer) Wadsworth uses silicon photovoltaic technology for light sensing. These sensors are accurate, durable, and economical. The sensors are protected in a plastic resin housing for indoor or outdoor use, and are cosine corrected to provide accurate readings at times of the day and year when the angle of the sun is low
