【Headers Not Soldered】AHT20+BMP280 3-in-1 Sensor Module for Temperature Humidity Pressure I2C
Key Features & Benefits
3-in-1 High Precision Measurement: Feature → Integrates AHT20 (T&H) and BMP280 (Pressure/T) sensors. Advantage → Simultaneously and accurately acquires three key environmental data points. Benefit → Provides comprehensive data for weather stations, environmental monitoring, saving cost and space.
Ready for Prototyping: Feature → Standard headers included. Advantage → After soldering, easily plugs into a breadboard or connects with jumper wires. Benefit → Very convenient for integration into your projects.
Low Power & Wide Voltage: Feature → Operating voltage as low as 2.8V-5V, very low power consumption. Advantage → Can be driven directly by 3.3V MCUs, perfect for battery-powered portable devices. Benefit → Extends your project's battery life.
Stable I2C Communication: Feature → Standard I2C digital interface output. Advantage → Strong anti-interference, stable transmission, supports multiple devices on the bus. Benefit → Clean wiring and high system integration.
Product Description:
This AHT20+BMP280 3-in-1 environmental sensor module is an ideal choice for your IoT projects. It integrates temperature, humidity, and barometric pressure sensing into a tiny board. We include the headers; you just need simple soldering to get started and acquire reliable environmental data via the I2C protocol.
Important Notes / How to Use:
【Must Read Before Purchase & Use】
【Critical Note】Headers Require Soldering: This product includes headers but they are NOT pre-soldered. Please ensure you have soldering capability before purchase. It's ready to use after soldering.
【I2C Addresses】Two Independent Addresses: There are two independent I2C devices. The fixed address for AHT20 is 0x38, and the default address for BMP280 is 0x76 (configurable to 0x77 via solder pad). Initialize both addresses correctly in your code.
Avoid Self-Heating Influence: Sensors are temperature sensitive. Install away from heat sources like CPUs, PMICs on your mainboard to ensure accurate temperature readings.
Pressure & Altitude: BMP280 measures absolute atmospheric pressure, which varies with weather and altitude. Calculating altitude requires a known sea-level reference pressure for conversion.
