This is an Arduino compatible sound level meter(also known as a decibel meter, noise meter). It uses an instrument circuit and low noise microphone, which enable it to accurately measure the sound level of the surrounding environment. It can be applied to environmental noise testing, such as highway noise monitoring stations, bedroom noise monitoring, etc.

Nowadays, there are many kinds of sounds surrounding, some of which are really noisy. It is really essential to measure whether the sound is noisy enough to do damage to our health.

The sound level meter (also known as the decibel meter, noise meter) is a basic noise measurement instrument. We have launched a sound level meter, which is compatible with Arduino, plug-and-play. It can accurately measure the sound level of the surrounding environment. This product uses an instrument circuit, low noise microphone, which makes it highly precise. It supports 3.3~5.0V wide input voltage, 0.6~2.6V voltage output. The decibel value is linear with the output voltage, which leads to a simple conversion, without a complex algorithm. The connector is plug-and-play, without welding, so this product can be easily used in your application.

The 103SR13A-1 is an unipolar hall-effect digital Position Sensor with 15/32-32 UNS-2A cylindrical aluminium threaded housing and 152mm (6-inch) 24-gauge stranded lead wires, irradiated polyethylene insulated termination. Meet NEMA 3, 3R, 3S, 4, 4X (stainless-steel housing), 12 and 13 requirements. They respond to the magnetic field from permanent magnets or electromagnets. This rugged non-contact sensing product use versatile, reliable Hall-effect sensor ICs that are operated by a magnetic field and are designed to respond to alternating North and South Poles or to South Pole only. The hall-effect position sensor includes latching and linear magnetic types. The standard open-collector sinking output (digital devices) or push-pull output (linear device) of the hall-effect position sensor can be easily interfaced with common electronic circuitry such as microprocessors, integrated logic, discrete transistors, and SCRs with compatible voltage specifications.

The DHT11 is a basic, ultra 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).

Its 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.
