Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The Waveshare Pico Environment Sensor is an add-on module that connects via a standard Pico header and communicates over the I2C bus using only two wires. It integrates five sensors: TSL2591 (light), BME280 (temperature/humidity/pressure), ICM20948 (9-axis motion), LTR390-UV (UV), and SGP40 (VOC). The module also includes voltage and logic-level translators (5 V to 3.3 V/1.8 V).<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL20232 WSAL20232 – Environment Sensors Module for Raspberry Pi Pico, I2C Bus]<br /> <br /> == Technical overview ==<br /> * Connection: plugs directly onto the Pico GPIO headers; communication over the I2C bus.<br /> * TSL2591: digital ambient light sensor for visible and IR light; I2C address 0x29; effective range 0–88000 lux.<br /> * BME280: temperature, humidity, and air pressure; I2C address 0x76; temperature range -40 to 85 °C (resolution 0.01 °C, accuracy ±1 °C); humidity 0–100 %RH (resolution 0.008 %RH, accuracy ±3 %RH); pressure 300–1100 hPa (resolution 0.18 Pa, accuracy ±1 hPa).<br /> * ICM20948: 9-axis motion sensor (accelerometer, gyroscope, magnetometer); I2C address 0x68; all channels 16-bit; accelerometer ranges ±2/±4/±8/±16 g; gyroscope ranges ±250/±500/±1000/±2000 deg/s; magnetometer range ±4900 µT.<br /> * LTR390-UV: UV light sensor; I2C address 0x53; response wavelength 280–430 nm.<br /> * SGP40: VOC sensor; I2C address 0x59; measuring range 0–1000 ppm ethanol equivalent; response time under 10 s (tau 63 %); start-up time under 60 s; supports humidity compensation.<br /> * Additional hardware: voltage translator from 5 V to 3.3 V/1.8 V and logic level translator from 3.3 V to 1.8 V.<br /> <br /> == Notes and version constraints ==<br /> * The source contains conflicting information about the motion sensor: specifications list ICM20948, while the “Sensor” section describes an MPU9250 instead – please verify which chip is actually onboard before publishing.<br /> * The source repeatedly mentions the Jetson Nano as the connection target despite this being a Pico module; this appears to be a copy-paste error and should be reviewed.<br /> * The demo code examples in the source reference external GitHub links and an Arduino Pico Core file; specific commands or scripts are not fully provided, so no commands were included.<br /> * The text contains marketing and navigation content (e.g., “Submit Now”, support hours) that has been removed.<br /> * The exact Python/C demo codes are truncated in the source; full usage requires consulting the original documentation.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/Pico-Environment-Sensor Pico Environment Sensor - Waveshare Wiki]<br /> * Source revision: 89773<br /> * Captured: 2026-09-02T03:34:25+00:00<br /> * SHA-256: &lt;code&gt;d8d1a49a779d8d78cc2c1b3dec4907a485935d021ce7cc0a855037c65f64d260&lt;/code&gt;</div>
