Wireless Temperature Sensors (Coin Cell)

The WEB ID coin cell wireless temperature sensors use either an external sensor probe or internal sensor probe to measure temperature with more accuracy and greater thermal range. Perfect for fast changing, temperature critical applications such as coolers or heaters. User customization allows you to set the frequency of readings and the ability to set thresholds for "Alarms", "Alerts" and "FYIs"

Refrigerated stock, food stuffs and medicines are your most valuable assets and require constant management to ensure stock is not kept out of safe temperature range, WEB ID have a wireless temperature sensor monitoring solution to suit any industry or environment.

Wireless Temperature Sensor Operation

The WEB ID Wireless Temperature Sensor outputs the ambient 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. To stay within the abilities of the processor, the temperature is computed off a data table provided by the manufacturer. To reduce error, the WEB ID Wireless Temperature sensor has a variable resistor configuration which is implemented over specified temperature ranges.

Wireless Temperature Sensor Caution/Notice:

This wireless temperature sensor is designed for applications in an ordinary environment (humidity and atmospheric pressure). Do not use this sensor under the following conditions as these factors can deteriorate the product characteristics and cause failures and burn-out.

• Corrosive gas or deoxidizing gas - chlorine gas, hydrogen sulfide gas, ammonia gas, sulfuric acid gas, nitric oxides gas, etc.).
• Volatile or flammable gas.
• Dusty conditions.
• Under low or high pressure.
• Wet or excessively humid locations.
• Places with salt water, oils chemical liquids or organic solvents.
• Where there are excessively strong vibrations.
• Other places where similar hazardous conditions exist.
Use this wireless temperature sensor within the specified temperature range. Higher temperature may cause deterioration of the characteristics or the material quality of the wireless temperature sensor.
