The ZS0501 is a digital temperature and humidity module that employs an NTC temperature-sensing element for temperature measurement and a polymer resistive humidity-sensitive element for humidity detection. Equipped with a high-performance microcontroller, the module outputs temperature and humidity data via a standard IIC protocol. It offers superior performance, ultra-fast response, robust anti-interference capability, and high cost-efficiency.

Application

Home Appliances: Household devices, humidity control systems, HVAC, dehumidifiers, smart thermostats, room monitors
Industrial Fields: Automotive industry, testing and inspection equipment, automatic control systems
Other Scenarios: Data loggers, weather stations, and other temperature/humidity detection and control applications

Features

High sensitivity and wide power supply range (3.3V to 5.5V)
Digital output with standard IIC serial interface, rapid response, and strong anti-interference ability
Excellent long-term stability, low power consumption, and high precision
