Altitude Tech K9Sense-NO₂ Gas Sensor Evaluation Kit is an ultra-low-power sensor kit that can target ammonia with low cross-sensitivity. The K9Sense-NO₂ sensor is based on 'Wake On Sense' technology that allows for real-time gas monitoring while consuming just a few µw of power. Altitude Tech K9Sense-NO₂ evaluation kit includes the INA317 µA instrumentation amplifier, AD5272BRMZ-100 Nano power ADC chip, and STM32 Cortex M0 processor under the hood. This nitrogen dioxide gas sensor kit offers 200µA low power in passive sense mode outputs such as temperature, relative humidity, and gas concentration. Typical applications include air pollution monitoring, indoor air quality, breath analysis, exhaust gas monitoring, gas alert system, environmental monitoring, diesel pollution, and Internet of Things (IoT).
