Elevate your DIY electronics and IoT projects with the SPeS-Modified DHT22 Temperature and Humidity Sensor (AM2302). Standard DHT22 sensors are notorious for “drowning” and locking up at 99.9% when exposed to continuous high humidity.

We custom-upgrade every module in-house before dispatch! Using a precise “Taco Fold” technique, we seal the internal sensor chip inside a professional 0.25µm ePTFE (expanded Teflon) hydrophobic membrane. This blocks liquid micro-droplets from ultrasonic foggers while remaining 100% permeable to water vapor. Now, your ESP32, Arduino, or Raspberry Pi projects can track harsh environments continuously without freezing or failing.

Why Choose the SPeS Modded DHT22?

• 💧 ePTFE Shielded: Hydrophobic barrier keeps liquid water off the sensor chip while allowing vapor to pass instantly. Perfect for mushroom fruiting chambers (RH > 90%).
• High Accuracy: Measures temperature from -40°C to 80°C (±0.5°C accuracy) and humidity from 0% to 99.9% RH (±2% RH accuracy).
• Wide Compatibility: Works flawlessly with ESP32, Arduino, Raspberry Pi, and other microcontrollers.
• Easy Integration: Uses a single digital pin for data output (1-Wire protocol) with a minimum sampling rate of 2 seconds.
• Low Power Consumption: Operates at 3.3V to 5.5V DC, drawing just 1.5 mA during measurement.

Applications

• Mushroom Cultivation: Designed specifically to handle 90%+ RH fruiting environments without freezing.
• Greenhouse & Propagation: Track ultra-humid propagation zones and misting tents.
• Smart Home & Weather: Robust outdoor weather stations that survive heavy rainfall and dew.
