The ES-13513 SHT45 sensor probe is a high-accuracy +-0.1C and +-1% RH, ultra-low-power, 16-bit relative humidity and temperature sensor probe for measuring relative humidity and temperature at different environmental conditions. Its I2C interface provides preconfigured I2C address 0x44 and maintains an ultra-low power budget. The power-trimmed internal heater can be used at three heating levels thus enabling sensor operation in demanding environments. The sensor is individually tested and calibrated and is identifiable by its unique serial number.

The surface of the SHT45 sensor probe is covered with a waterproof and breathable membrane to protect it. The shell is waterproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity (moisture) of the environment. It has been widely used in HVAC, consumer goods, weather stations, test & measurement, automation, medical, and humidifiers, especially performing well in extreme environments like acid, alkali, corrosion, high temperature, and pressure.

The probe connector is Mini Round Shell MRS type and the wire length is 1 meter.

Product FAQ
Q: What is the common use of a Temperature and Humidity Sensor?
A: Temperature and Humidity sensors are among the most commonly used environmental sensors. It is widely used to provide the actual humidity condition within air at any given point or in any given place. Such devices are commonly used in situations in which air conditions may be extreme or where air conditions need to be controlled due to varying reasons.

Q: Why is Temperature and Humidity sensors important in some industries?
A: Humidity is the presence of water within the air. Measuring humidity within the environment can be critical due to the fact that the higher the humidity, the warmer it may seem. In industries, humidity measurement is often important because it can affect the health and safety of personnel as well as the cost of the product. As a result, temperature and humidity sensors are often quite important.

Q: How do I choose a suitable Temperature and Humidity Sensor?
A: There are some important specifications you might need to consider when you choose this product. This includes:
  • Accuracy
  • Long-term stability
  • Ability to recover from condensation
  • Resistance to physical and chemical contaminants
  • Interchangeability
  • Repeatability
