Heart Beat Pulse Sensor

Heart Rate data can be used in many Electronic design and microcontroller projects. But the heart rate data is difficult to read, however, the Pulse Sensor Amped help us to read heart rate. The Heart Beat Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino.

It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.

Pulse Sensor Amped adds amplification and noise cancellation circuitry to the hardware. It’s noticeably faster and easier to get reliable pulse readings. Pulse Sensor Amped works with either a 3V or 5V Arduino.

Pulse Sensor Arduino Hookup

Connect the sensor’s power supply pins to the Arduino board supply pin as Red – 5V, Black – GND and Purple – A0 (analog input 0) its over. This Analog input reading can be displayed in the serial terminal of Arduino IDE or it can be drawn as the pulse by using Processing IDE.

Features :

1. A Color-Coded Cable, with a standard male header connectors. Plug it straight into an Arduino or a Breadboard. No soldering is required.
2. The Pulse Sensor has 3 holes around the outside edge which make it easy to sew it into almost anything.
3. Visualization software (made in Processing) to instantly see the output of the sensor and for troubleshooting.

Package Includes :

1 x Heart Beat Pulse Sensor

The Water Level Depth Detection Sensor for Arduino has Operating voltage DC3-5V and Operating current less than 20mA. The Sensor is the Analog type which produces analog output signals according to the water pressure with its Detection Area of 40x16mm.

The Water Level Sensor is an easy-to-use and cost-effective with high level/drop recognition sensor by having a series of parallel wires exposed traces measure droplets/water volume in order to determine the water level.

Easy to complete water to analog signal conversion and output analog values can be directly read Arduino development board to achieve the level alarm effect.

Package Includes :

1 x Water Level Sensor Depth of Detection Water Sensor for Arduino

Sound Detection Module Sensor for Intelligent Vehicle Compatible With Arduino is a Single channel signal output Sensor. The output is effective to the low-level sound signal with good fidelity, When there is sound, outputs low level and signal light.

It can be used for Acoustic control light, give sound and light alarm working with the Photosensitive sensor, and sound control, sound detect. (The Maximum induction distance is 0.5M)

Note: This sensor only recognizes the availability of sound (vibration principle) cannot identify the size of the sound or the specific frequencies of sound.

Features :

1. Uses LM393, Electret condenser microphone
2. Signal output Indication
3. Single channel signal output
4. The output effective signal is low level.
5. Can detect the intensity of the sound environment
6. With the retaining bolt hole, convenient installation.

If you are searching for a Gas sensor module with a very High detection range compared to any ordinary gas sensor then this MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module will fulfill your specification demands. The MQ-2 Gas sensor detector module has a detection range of 300-10000 ppm. The gas sensor modules are always well known for their robust and simple construction and measures toxic gases in very low concentrations.

The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer.

MQ-2 gas sensor using gas sensitive material is to be clean air in the lower conductivity of stannic Oxide or tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the conductivity of the sensor with an increasing concentration of combustible gas in the air increases.

Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas.

MQ-2 gas sensor higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas, and other combustible vapors are ideal. This sensor can detect a variety of flammable gas, is a low-cost sensor for many applications.

Following conditions must be avoided

Water Condensation
Indoor conditions, slight water condensation will affect sensors’ performance lightly. However, if water condensation on sensors surface and keep a certain period, sensor’ sensitivity will be decreased.

Used in high gas concentration
No matter the sensor is electrified or not if a long time is placed in high gas concentration it will affect the sensor’s characteristics.

Longtime storage
The sensor’s resistance produces reversible drift if it’s stored for a long time without electrifying, this drift is related to storage conditions. Sensors should be stored in airproof without silicone gel bag with clean air. For the sensors with long time storage but no electrify, they need a long aging time for stability before using.

Longtime exposed to an adverse environment
No matter the sensors are electrified or not, if exposed to an adverse environment for a long time, such as high humidity, high temperature, or high pollution, etc, it will affect the performance of the sensor badly.

Vibration
Continual vibration will result in sensors’ down-lead response then rapture. In transportation or assembling lines, a pneumatic screwdriver/ultrasonic welding machine can lead to this vibration.

Concussion
If sensors meet strong concussion, it may lead its lead wire disconnected.

If you are wandering to build a device that detects temperature and humidity from the atmosphere, then This sensor is needed for you. you can Purchase this sensor from Robu.in at a reasonable price.

The DHT22 Digital Temperature and Humidity Sensor Module AM2302 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

It’s fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Features :

1. High precision
2. Capacitive type
3. Full range temperature compensated
4. Relative humidity and temperature measurement
5. Calibrated digital signal
6. Outstanding long-term stability
7. Extra components not needed
