Sensaphone Offers New Sensors to Monitor Humidity, CO2 and Dew Point in Harsh Greenhouse Environments

ASTON, Pa., May 17, 2018 – To keep plants alive and healthy, greenhouse operators must maintain the best possible growing atmosphere. Remote monitoring systems monitor all critical conditions in greenhouse environments. They provide 24/7 monitoring, real-time visibility and instant notification of potential threats to inventory. But greenhouse managers must make sure that the equipment can withstand harsh conditions. That's why Sensaphone® introduced three new sensors for greenhouse applications. Each sensor features a weatherproof enclosure to prevent damage to sensitive electronics.

The Sensaphone Outdoor Humidity Sensor monitors humidity levels and is compatible with any Sensaphone device that accepts a 4-20mA signal. With a range of 0% to 100% relative humidity level, this sensor sends a signal to the monitoring system when the humidity exceeds or falls below the set limit. The system then immediately notifies designated personnel. The sensor is mounted in a weatherproof enclosure for operation in harsh environments.

The Sensaphone Outdoor CO2 Sensor detects levels of carbon dioxide from 0-20,000 ppm. It is ideal for applications where higher levels of CO2 are a concern (>2,000 ppm), such as greenhouses or livestock buildings. When used with any Sensaphone monitoring device that accepts a 4-20mA input signal, the sensor provides real-time CO2 data. When the CO2 level reaches a set threshold, the sensor causes the monitoring device to activate an alarm. The weatherproof enclosure allows users to place the sensor in areas where the environment would typically shorten the life of unprotected sensors.

The Sensaphone Dew Point Sensor measures and provides real-time dew point values to any Sensaphone device that accepts a 4-20mA signal. When the dew point level falls outside of the preset range, users receive an alarm indicating the current dew point value. The sensor is enclosed in a weatherproof enclosure, making it suitable for indoor and outdoor environments. Users can select from three dew point ranges: -22° to 122°F (-30° to 50°C); -4° to 104°F (-20° to 40°C); or 32° to 122°F (0° to 50°C).
