MQ-8 Hydrogen Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. The MQ-8 hydrogen gas sensor is suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm. This sensor has a high sensitivity and fast response time.  Note ...

MQ-5 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. This MQ-5 gas detector is used for leak detection of LPG  (Liquified Petroleum Gas), natural gas and city gas. It has low sensitivity to alcohol and smoke. Note After turning on the module, wait 2 minutes for the internal heater to warmp up. You can download the datasheet of this module here.[wpdm_...

MQ-4 Smoke Gas Module Features MQ series sensors use a small heater inside with an electrochemical sensor in order to measure different kinds of gases combination. This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. MQ-4 has a high switching speed, no noise when switching, and also has a long life. It has a low sensitivity to alcohol and smoke. The sensor normally has a zero output, and its output inc...

MQ-3 Alcohol Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combination. The MQ-3 sensor is one of the MQ series heater-driven gas sensors that has an internal variable resistance from pin A to pin B, which depends on the amount of alcohol in the air. The sensor's output is an analog resistance. This sensor can measure the alcohol concentration in human blood alcohol gas on your breath. Alcohol decreases the i...

MQ-135 Smoke Gas Sensor Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure different kinds of gas combinations. The MQ-135 sensor is a sensor for detecting air quality. This sensor is able to detect smoke, CO2, ammonia, alcohol and benzene in the air. Note After turning on the module, wait for 2 minutes until the inside heater warms up. You can download the datasheet of this module here.[wpdm_package id=...

TSD-10 Thermometrics Turbidity Sensor Features The TSD-10 turbidity sensor measures the turbidity using optics and light passing through the liquid. This sensor has an analog output and requires an ADC converter. It is used in washing machines to measure the density of water turbidity. By using an optical transistor and optical diodes, it measures the amount of light coming from the source of the light to the light receiver, in order to calculate water turbidity. This sensor has a waterproof body. Note You ...

YZC-161B Load Cell Sensor Features Load cells are electronic sensors used for measuring weight and force. Load cells are made of alloy and a number of tensile strengths. When force is on the load cell, the spring element is slightly deformed, and unless overloaded, always returns to its original shape. The capacity of a load cell is the maximum amount of force it can withstand. Notes To measure tensile strength changes, we use the HX711 module. It is a high-precision analog-to-digital converter...

YF-S201 Water Flow Sensor Features YF-S201 is a sensor used to measure the water flow. This water flow sensor mainly consists of a plastic valve body, rotor assembly, and a hall effect sensor. This module works based on the hall magnetic effect. So when the water flows through the rotor assembly, the rotor will rotate and the hall effect sensor will produce an electric pulse. By counting these generated pulses, the amount of water passing through the sensor can be calculated.The measuring range of wat...

MAX30102 Heart Rate Module Features MAX30102 sensor is used to detect blood oxygen and heart rate. First, infrared radiation is sent and reflected by hitting the finger, and then the amount of oxygen in the blood is determined by measuring the wave amplitude. Heart rate is also obtained by analyzing the time series response of this radiation.The MAX30102 is an integrated module compatible with the Arduino and STM32. It integrates a red LED with an infrared LED, a photoelectric detector, an optical devi...
