HCSR04 Ultrasonic Sensor. This is the HCSR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of noncontact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HCSR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HCSR04: VCC (Power), Trig ...

20180503· The first thing we need to do is obtaining the reading from the analog pin connected to the sensor. To do it, we simply call the analogRead function, passing as input the number of the pin we previously defined. int adcVal = analogRead(analogPin); As mentioned before, this will correspond to a value between 0 and 4095 (the ADC has 12 bits), which we will need to convert to a voltage. …

Before we can use this formula in a sketch, we need to determine R0 of the MQ7 sensor first. This varies between devices so there is a need for actual testing. From the loglog plot, we can see that RS/R0 is constant in air and is equal to 1. Since by definition, R0 is the resistance of the sensor in clean air, then only RS varies for every gas.

20160617· Connect the CO (MQ7) gas sensor. *Aside: The MQ7 sensor requires cycling the heater voltage (H1) between (for 90s) and 5V (for 60s). One way to do this is to use a relay triggered by the Photon (with the aid of a MOSFET and potentiometer) when the relay is not powered, the voltage across H1 is 5V, and when the relay is powered the voltage across H1 is ~
