INA169 Analog DC Current Sensor Breakout - 60V 5A Max

OverviewPinoutWiringRelated groups
INA169 Analog DC Current Sensor Breakout - 60V 5A Max — Adafruit — 1164

This breakout board will solve all your current-monitoring problems. Instead of struggling with a multimeter, you can just use the handy INA169 chip on this breakout to both measure both the DC current draw and have a handy analog output that is with respect to ground.

Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.
