The CH34X family comprises widely used USB‑to‑serial chips manufactured by WCH (WinChipHead), commonly integrated into generic UNO R3, ESP8266, and ESP32 development boards.
Overview
- MIXED SENSOR BUNDLE (3x DHT22 + 3x DHT11) Includes 3 DHT22 sensors for applications like weather stations or greenhouses, and 3 DHT11 sensors for basic indoor monitoring, organized in a storage container.
- CALIBRATED DIGITAL OUTPUT Calibrated digital outputs for temperature and humidity readings — for Arduino, Raspberry Pi, ESP32, and other MCU-based DIY electronics.
- GOLD IMMERSION PLATING Gold-plated contacts for corrosion resistance and signal integrity in humid environments. Lead-free, RoHS-compliant.
- WIDE COMPATIBILITY (3.3V–5V) Works with microcontrollers operating on 3.3V to 5V (up to 6V for DHT22), using single-wire digital communication — no extra components needed for most projects like smart home automation or data logging.
- DHT22 vs DHT11 SPECS DHT22: -40°C to 80°C, 0–100% RH, ±0.5°C/±2% accuracy for precise needs. DHT11: 0–50°C, 20–80% RH, ... Read More...
