In today's rapidly developing Internet of Things (IoT) era, accurate environmental sensing is the core foundation for intelligent devices to achieve efficient and automated control. Whether ensuring the comfort and health of smart homes or guaranteeing the stability and reliability of industrial processes, a high-performance, highly reliable temperature and humidity sensor is crucial. Today, we proudly recommend Tensensor's star product—the WHT20 temperature and humidity sensor, which, with its superior performance and wide applicability, will become the ideal sensing unit for your projects.

WHT20 MEMS type Temperature and Humidity Sensor

    The WHT20 is a digital temperature and humidity sensor based on advanced integrated circuit technology. It condenses high-precision detection capabilities into an ultra-small SMD package, designed for the compact design and efficient production of modern electronic devices.

Core advantages

    High precision and reliability: Under typical conditions, it achieves humidity measurement accuracy of ±3.0% RH and temperature measurement accuracy of ±0.5℃. Utilizing a unique humidity sensing mechanism and Vbe transistor temperature measurement technology, it maintains excellent stability even in long-term high-humidity environments, providing you with a reliable data foundation.

    Miniaturized design for easy integration: Measuring only 3.0mm x 3.0mm x 1.05mm in a dual in-line flat leadless package, it perfectly adapts to reflow soldering processes, greatly simplifying PCB design and manufacturing assembly, making it especially suitable for space-constrained portable or miniaturized devices.

    Low power consumption and energy efficiency: Supporting a wide voltage supply from 2.0V to 5.5V, with a current as low as 240nA in sleep mode and an average power consumption of only about 3.3μW, it significantly extends the battery life of battery-powered devices, making it an excellent choice for IoT nodes.

    Digital interface, simplified development: Directly outputs calibrated digital signals using the industry-standard I²C communication protocol, eliminating the need for complex analog signal conditioning circuits. This significantly reduces system design complexity and the burden on the microcontroller, accelerating product time-to-market.

    Strong environmental adaptability: Operating over a wide range of -40℃ to 85℃ (temperature) and 0% to 80% RH (humidity), it can recover performance after brief exposure to extreme conditions through specific treatments, adapting to various application scenarios.

Application Scenarios

    Smart Home: Air conditioners, dehumidifiers, humidifiers, thermostats, air purifiers, and smart environmental monitoring devices enable automatic adjustment and optimization of the indoor environment.

    Industrial Control: Industrial automation equipment, testing and measuring instruments, data loggers, and warehouse environment monitoring ensure optimal production and storage conditions.

    Consumer Electronics: Weather stations, wearable devices, and smart agricultural monitoring points provide accurate environmental data.

    Other Fields: Medical equipment, laboratory instruments, ventilation systems, and any other application requiring temperature and humidity monitoring.

    The WHT20 is more than just a sensor; it's a well-thought-out "plug-and-play" solution. It successfully strikes the optimal balance between high accuracy, small size, low power consumption, and ease of use. Choosing the WHT20 means selecting a stable and reliable environmental sensing core for your products, bringing a smarter and more comfortable experience to end users.

    Whether upgrading existing products or developing entirely new smart devices, Tensensor's WHT20 temperature and humidity sensor deserves your in-depth evaluation. Its comprehensive technical documentation and reliable product quality will safeguard your designs and help you gain a competitive edge in the market. Please contact us if you have any needs:
