SENSEIOT VSM-180C SMD Integrated Temp-Humidity & VOC Air Quality Module

Specifications

Product Introduction

The VSM180C is a TVOC sensor module designed for accurate detection of volatile organic compounds. It supports both IIC and UART communication interfaces, making it suitable for a wide range of environmental monitoring applications. The module is compact and designed for easy integration via stamp hole soldering.

Features

  • Uses stamp hole SMD soldering for secure mounting
  • IIC interface requires external pull-up resistors of 4.7K ohms
  • UART interface is read-only; TXD connects to the customer's MCU RX, RXD is not connected
  • Provides equivalent CO2 and TVOC concentration data
  • Simple communication protocol for data retrieval

Applications

  • Indoor air quality monitoring
  • HVAC systems
  • Smart home devices
  • Portable air quality detectors
