Wireless Temperature and Humidity Sensors

Wireless Temperature Sensor

The ALTA Wireless Temperature Sensor uses a type NTC thermistor to measure temperature. It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, send power to the NTC Thermistor and wait for it to stabilize, and convert the analog data, mathematically compute the temperature and transmit the data to the gateway.


Wireless Temperature Sensor with Probe

The ALTA Wireless Temperature Sensor uses a 3-foot lead to measure temperature. It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, send power to the NTC Thermistor and wait for it to stabilize, and convert the analog data, mathematically compute the temperature and transmit the data to the gateway.


Wireless Thermocouple

The ALTA Wireless Thermocouple Sensor is available with a hardwired thermocouple or K-type connector to support various thermocouple types and ranges. The hardwired thermocouple option measures temperatures up to 1100°C (2012°F).


Wireless High Temperature Sensor

The ALTA Wireless High Temperature Sensor uses a glass coated platinum RTD sensor to accurately measure temperatures from -50°C to +370°C (-58°F to 700°F). It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, power up the RTD sensor and wait for it to stabilize then mathematically compute the temperature and transmit the data to the gateway.


Wireless Low Temperature Sensor

The ALTA Wireless Low Temperature Sensor uses a glass coated platinum RTD sensor to accurately measure temperatures from -200°C to +162°C (-328°F to +325°F). It is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, power up the RTD sensor and wait for it to stabilize then mathematically compute the temperature and transmit the data to the gateway.


Wireless Water Temperature Sensor

The ALTA Wireless Water Temperature Sensor uses a sealed, type NTC thermistor with 3 ft. lead wires to measure water temperature. The ALTA Wireless Water Temperature Sensor can collect temperature data of water or other non-combustible liquids using a sealed NTC thermistor with 3 foot lead wires.


Wireless Duct Temperature Sensor

The ALTA Wireless Duct Temperature Sensor uses an NTC thermistor with 8 ft. lead wires to accurately measure temperatures in duct work, while maintaining a sealed environment. Can be easily installed and mounted for long term use.


Wireless Humidity Sensor

The ALTA Wireless Humidity (RH) Sensor allows you to accurately monitor the relative humidity of the air within a room or enclosure. The ALTA Wireless Humidity (RH) Sensor measures the relative humidity at the device and returns RH and temperature values.

Wireless Water Sensors

Wireless Water Sensor

The ALTA Wireless Water Detection Sensor detects the presence or non-presence of water. The ALTA Wireless Water Detection Sensor detects when water is present by completing the circuit between the two leaded wires.


Wireless Water Rope Sensor

The ALTA Wireless Water Rope Sensor detects the presence of water anywhere along the surface of the rope. Sensor comes with 10 feet of water rope. Additional 10 ft. sections are available and can be connected up to 100 feet.


Wireless Security

Wireless Dry Contact Sensor

ALTA wireless dry contact sensors can be used to detect contact between two wired contact points, an external mechanical switch or a contact plate. It can easily be integrated into existing switches or contact plates.


Wireless Open / Closed Sensor

The ALTA Wireless Open / Closed Sensor can be used to detect when a door or window is opened and closed using a magnetic switch. When the sensor detects that the magnet is removed or returned it sends the information to the your monitoring and notification system.


Wireless Button Press Sensor

The ALTA Wireless Button Sensor detects when the button has been pressed, triggering a notification from the system. Example applications include hotel/motel front desk call button, restroom service/clean-up request button, service request button, and more.
