Engineered for professional-grade environmental sensing, the SHT40 Sensor Probe delivers unparalleled precision in temperature and humidity measurement. Designed with a compact stainless-steel porous housing, this sensor ensures reliable operation in a wide range of harsh and high-pressure environments, including industrial pipelines, HVAC systems, test chambers, and high-humidity zones. With its ultra-low power consumption, 16-bit resolution, and digital I2C output (preset at address 0x44), the SHT40 is a dependable solution for both embedded and industrial applications requiring continuous, long-term stability.

Every unit is individually calibrated and tested, carrying a unique serial number for traceability. The integrated breathable membrane effectively shields internal components from particulates, moisture, and corrosive agents, while allowing accurate airflow for responsive sensing. Enhanced by a variable power heater and full operability in condensing environments, the sensor remains dependable in critical-use cases such as medical devices, automation systems, and explosive zones containing dust or gases.

Digital Humidity and Temperature Sensor Probe Applications

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:
