Humidity & Temperature Sensor

A Humidity & Temperature sensor, by the name suggests, is an electronic device that measures the humidity & temperature element in its environment and converts its findings into a corresponding electrical signal. They are used in automobiles, medical devices, computers, cooking appliances, and other types of machinery.

Humidity sensors vary widely in size and functionality; some humidity sensors can be found in handheld devices (such as smartphones), while others are integrated into larger embedded systems (such as air quality monitoring systems). They are commonly used in the meteorology, medical, automobile, HVAC and manufacturing industries. Some temperature sensors require direct contact with the physical object that is being monitored while others indirectly measure the temperature of an object (non-contact temperature sensors).  Non-contact temperature sensors are usually infrared (IR) sensors. They remotely detect the IR energy emitted by an object and send a signal to a calibrated electronic circuit that determines the object’s temperature. Among the direct contact temperature sensors are thermocouples and thermistors.

 

Different Types of Temperature Sensor:

Thermistors are very small in size. Their sensing element is either glass or epoxy, ceramics or polymers coated and have 2 wires, to be connected to an electric circuit. They measure temperature by measuring the change in resistance of the electric current. Thermistors are available as either NTC or PTC and are often low cost. Thermistors are more precise than thermocouples (capable of measuring within 0.05-1.5 degrees Celsius)

 

RTDs or Resistance Temperature Detectors work has 2 wires to measure change in resistance of electric wire and measure ohmic resistance to measure temperature. They are connected to a circuit in a similar way to a thermistor but they have a much wider temperature range and can measure extreme temperatures. (RTD) are essentially the metal counterpart of thermistors, and they are the most precise and expensive type of temperature sensors.

 

Thermocouples use two conductors, made up of different metals that are joined at the end to form a junction. When this junction is subjected to heat, a voltage is produced that is directly proportional to the temperature input. They are highly versatile as different metal combinations allow for different measurement ranges; however, they lack the fine accuracy of NTC’s and RTD’s making them the least precise out of the three types. Thermocouples are generally inexpensive, as their design and materials are simple.

 

Temperature Probes are a very common and diverse type of temperature sensor. They consist of either a thermistor, a thermocouple or RTD sensing element and can be finished with a terminal head. All three types of sensors can be manufactured into a variety of housing. This allows for enhanced utility, that may span over a multitude of different environments and media that they encounter.

 

Uses:

• auditing of the status of the equipment.
• increasing product safety
• fine-tuning of the rooms’ conditions through the Building Management System (BMS)
• adding humidity sensors to HVAC systems and office environments, Facilities Managers can efficiently monitor, measure, and adjust humidity to provide a comfortable and productive working environment.
• Beyond comfort, humidity sensing is essential to ensuring proper conditions for valuable assets. For example, galleries, museums, offices, hotel rooms, cold storage, etc
• track of humidity changes, as moisture can be catastrophic for paintings, drawings, prints, mosaics, and sculptures. Humidity monitoring helps galleries and museums protect their assets and lower their insurance costs.
• intelligent asset management use cases. They can be deployed on assets (e.g., pumps, compressors, fans, data centers) to facilitate a transition from preventive to predictive maintenance.
• real-time monitoring of humidity to identify problems (e.g., potential leakages) before they occur.
