DHT11 humidity temperature sensor set + ESP-01S WiFi ESP8266EX module

This practical kit consists of two key components: the DHT11 sensor and the WiFi module ESP-01S, which together form a comprehensive tool for environmental monitoring and remote data reporting. The DHT11 sensor provides precise measurements of temperature from 0 to 50°C and humidity from 20 to 90%, with a resolution of 1°C and 1% respectively. It features measurement accuracy of up to ±2°C for temperature and ±5% for humidity, and the sensor's response time is only 10 seconds for temperature and 6 seconds for humidity. Based on the ESP8266EX processor, the ESP-01S module offers strong network support through compatibility with WiFi 802.11 b/g/n, operating at frequencies from 2.4 to 2.5 GHz. It supports standard network protocols such as IPv4 and TCP/UDP/HTTP for easy integration into home or industrial automation systems. The module has a built-in PCB antenna and supports various WiFi modes, including AP, STA and AP+STA, with a maximum transmitter power of up to 20 dBm. With its compact size and UART interface that allows easy programming and communication with external microcontrollers, this kit is ideal for smart home applications, building automation systems and various hobby projects where remote monitoring and environmental control are key.
