Highly accurate digital sensing technology: MS1100 gas sensor uses advanced ASIC dedicated chips and MEMS semiconductor capacitive humidity sensing elements to accurate detection of TVOC gases such as carbon dioxide and formaldehyde in home or laboratory environments. Designed for multi-environment detection: This sensor is suitable for kitchens, bedrooms and work spaces, etc. It can detect gas concentrations ranging from 0 to 1000ppm, and has high sensitivity and excellent stability for gas concentrations of 0.1ppm and above. Adjustment and customization threshold function: working voltage is DC 5V, working current is 100mA, and the output analog signal range is 2.6-5V. Users can adjust the sensitivity as needed and set specific sensor thresholds to adapt to different monitoring needs. Easy access and application: The simple interface connection method allows the MS1100 module to be easily connected to microcontrollers, making it suitable for electronic DIY enthusiasts and engineers to develop and expand environmental monitoring systems. Compatibility and Safety Tips: Please note that this product is designed to comply with U.S. standards, please make sure its voltage and socket comply with your region's standards before use. Verify product compatibility before purchasing, adapters or converters may be required.
