This little breakout contains two chips that sit sidebyside to provide 9 degrees of full motion data. The board includes an LSM6DS33 , a 6DoF IMU accelerometer + gyro.
Abstract: Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx adsorber and SCR aftertreatment.
Alphasense NO2 Sensors . Alphasense Nitrogen Dioxide Sensors (NO2 Sensors) are available in a wide range of formats and both PPM and PPB variants, making them suitable for use in variety of applications, from fixed and portable detection instruments to environmental monitoring systems and networks.

What range of concentrations of NO 2 will you be measuring? Which Arduino model are you using? The sensor outputs current proportional to the concentration of NO a look at in the shows the voltages for different concentrations of NO 2, if you run connect a 33Ω load resistor from the sensor output to GND.. Notice the offset: 0ppb corresponds to 170mV.

The Formaldehyde (HCHO) sensor is an Arduino Raspberry Pi compatible module, which is the ideal solution for indoor air quality monitor. This is a HCHO (CH2O) sensor module. It can be used to measure HCHO in air. Through it, you can know the air quality. This sensor module is widely used in many air testing applications, such as indoor air ...
Which CO2 Sensor is Right For You? For indoor air quality projects, indoor greenhouses, student projects, or connecting to Arduino or Raspberry Pi, the fastest and easiest way to accurately measure carbon dioxide is the COZIR Ambient Air CO2 Sensor Development kit includes a GSS COZIR sensor, an FTDI USB cable with a connector, and our free GasLab® software.
20/4/2019· There are three types of resistive touch sensors: 4 – wire, 5 – wire and 8 – wire. 4 – Wire resistive touch sensor is most cost effective. 5 – Wire resistive touch sensors are most durable. They are similar to 4 – wire sensors except that all the electrodes in this type are on the bottom layer.
The Black Pulse Heartbeat Heart Rate Sensor Module is a plugandplay heart rate sensor. It can be used by students, artists, athletes, makers, and game mobile developers who want to easily incorporate live heartrate data into their essentially combines a simple optical heart rate sensor with amplification and noise cancellation ...
6/5/2021· Hello, I am looking for probes for determining the amount of ammonia, nitrite, and nitrate present in a liquid. Specifically, I''m looking for something I can use to monitor (not adjust, just monitor) the chemical status of my fish tank. Googleing hasn''t found me anything but the MQ137 which is a gas sensor for ammonia, not liquid.

16/2/2018· Features of the MQ sensors. Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...
