OE#SPS30 Micro Dust/PM Sensor Module, 5V Supply, 55mA Avg, UART/I2C, 5-Pin, PM1 PM2.5 PM4 PM10 Digital Output, for Air Purifier HVAC Monitor

SPS30 Micro Dust / Particulate Matter Sensor Module (Replacement for OE#SPS30)Designed for air-quality monitoring devices such as air purifiers, ventilation systems, and HVAC controllers. Please verify compatibility by OE/model number and your device manual before ordering.Key SpecsSupply voltage: 4.5-5.5V (5V nominal)Interfaces: UART or I2C (select via SEL pin)Connector/pins: 5-pin (VDD, RX/SDA, TX/SCL, SEL, GND)Average supply current: <60mA @ 1 Hz samplingOutputs: digital particulate measurements (PM1.0, PM2.5, PM4, PM10) and particle count binsSize: 40.6 x 40.6 x 12.2mmInstallation NotesDisconnect power before servicing; avoid static discharge and keep inlet/outlet unobstructed.Set SEL before power-up: SEL floating = UART, SEL to GND = I2C. Use short I2C wiring or choose UART for longer cables.After replacement, allow a brief stabilization period and check that readings update normally.Common Symptoms of a Failing SensorDevice reports a sensor error or no PM readingReadings stuck at a constant value or fluctuate abnormallyAir-quality display does not update after power cycleNote: This is a replacement sensor module. Performance depends on the host device design, airflow path, and firmware settings. Confirm fitment by OE#SPS30 and your device documentation.

• Technical Specifications: Particulate matter (micro dust) sensor module replacement for OE#SPS30; supply 4.5-5.5V (5V nominal), digital interface UART or I2C, average supply current <60mA @ 1 Hz sampling; calibrated digital output for mass concentration PM1.0 / PM2.5 / PM4 / PM10 and particle number concentration bins; compact 40.6 x 40.6 x 12.2mm; designed for long-term air-quality monitoring in air purifiers, ventilation, and HVAC control. Confirm your original part/model number and connector/pinout before purchase
• Installation and Replacement Guidelines: Power off the device and discharge static; mount so the air inlet/outlet are not blocked and keep the flow path unobstructed. 5-pin wiring: VDD, RX/SDA, TX/SCL, SEL, GND - verify pinout against your device manual. Select interface before power-up: leave SEL floating for UART; pull SEL to GND for I2C. For cabled installs, keep I2C leads short (<10 cm) or use UART for better noise immunity; after installation allow a brief stabilization period and confirm readings update normally
• Digital Output Capabilities: Provides calibrated digital measurements for multiple particulate matter sizes including PM1.0, PM2.5, PM4, and PM10 mass concentrations, plus particle number concentration bins for comprehensive air quality analysis
• Dual Interface Options: Supports both UART and I2C communication protocols selectable via SEL pin configuration, offering flexibility for integration with various host devices and system architectures
• Compact and Energy Efficient Design: Measures only 40.6 x 40.6 x 12.2mm with low power consumption of less than 60mA average current at 1 Hz sampling rate, suitable for continuous air quality monitoring applications
