ZS13 is a brand new product, which is equipped with special ASIC sensor chip, high-performance semiconductor silicon-based capacitive humidity sensor and a standard on-chip temperature sensor, it uses standard I²C output signal format. ZS13 products have stable performance in high temperature and high humidity environment; At the same time, the product has great advantages in accuracy, response time and measurement range. Each sensor is strictly calibrated and tested before leaving the factory to ensure and meet the large-scale application of customers.


  • Home appliance fields: HVAC, dehumidifiers, smart thermostats, and room monitors etcs;
  • Industrial fields: Automobiles, testing equipment, and automatic control devices;
  • Other fields: data loggers, weather stations, medical and other related temperature and humidity detection devices.


  • Fully calibrated
  • Wide power supply voltage range, from 2.2V to 5.5V
  • Digital output, standard I²C signal
  • Quick response and strong anti-interference ability
  • Excellent long-term stability under high humidity condition

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
