WS16 AS3935 2.4V to 5.5V Lightning Distance Detector sensor (lightning sensor)
Based on the AMS reference design, this is a breakout board for the AS3935 digital lightning sensor. With a specially tuned antenna, SPI or I2C interfacing and a wide 2.4V to 5.5V standard operating range, this innovative sensor is designed to interface with most current development systems and boards. This includes all of the current Arduino modules!
 
The AS3935 Franklin Lightning Detector gives you lightning detection for your next weather project. This sensor is capable of detecting lightning up to 40 km away with an accuracy of 1km to the storm front! On the product is a sensitive antenna tuned to pick up lightning events in the 500kHz band. When sensing an event the AS3935 utilizes an interrupt to the interrupt pin, distinguishes between false and real lightning events, and has a number of features to help calibrate lightning detection. For example, there are settings for detecting from indoors or detecting from outdoors, settings to change the threshold for false events, and settings to be alerted only after a certain number of lightning strikes to name a few. We've also written an Arduino Library to get you prepared for that upcoming storm!
 
The product is capable of communicating over SPI or I2C and sports a Qwiic connector for fast implementation without the need for soldering.

PMS5003 Particulate Matter Sensor with Cable (particulate sensor)

Monitor air pollution cheaply and accurately with this matchbox-sized particulate matter (PM) sensor from Plantower! It senses particulates of various sizes (PM1, PM2.5, PM10) from sources like smoke, dust, pollen, metal and organic particles, and more.

Pair this particulate matter sensor with our Enviro plus and build your own air quality monitoring station to contribute to citizen science. Just plug the cable into the sensor and then into the connector on the underside of Enviro plus, and away you go!

The sensor has a small fan that sucks air through the sensor and past a laser that can detect both the number (and hence concentration) and size of particles in the surrounding air.

Features

  • Plantower PMS5003 Particulate Matter (PM) Sensor (datasheet)
  • Detects PM1, PM2.5, PM10 particulates
  • 15cm Picoblade cable
  • UART serial interface
  • Python library
  • Dimensions: 50x38x21mm

Software

Our Python library for the PMS5003 sensor lets you read PM1, PM2.5, and PM10 in both standard and environmental units, and numbers of particles of various sizes: >0.3, >0.5, >1.0, >2.5, >5, and >10um.

Note that if you're using this sensor with Raspberry Pi, then you'll need to make a couple of changes to its configuration. Type sudo raspi-config in the terminal and then under "Interfacing options" and "Serial" disable the login shell and enable the serial port hardware. Edit your /boot/config.txt file and add the lines enable_uart=1 and dtoverlay=pi3-miniuart-bt to the bottom of the file.

Our Enviro plus installation script will do all of this configuration for you.

Notes

There's a blue protective film that covers the metal casing of the sensor, and you can peel this off before use.

DC Voltage detection Sensor (DC Volt sensor)
Introduction:

This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, A rduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because A rduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.
    
    Parameters:
    Voltage input range: DC0-25V
    Voltage detection range: DC0.02445V-25V
    Voltage analog resolution: 0.00489V

    Wiring:
    DC input connector:
    
    the positive terminal connected to VCC,
    the negative  connected to GND
    Output interface:
    "+" is 5 / 3.3V,
    "-" then GND,
    "s" Arduino connected to the AD pin


    Arduino Code:

    #include


    int val11;
    int val2;

    void setup()
    {  
     pinMode(LED1,OUTPUT);  
     Serial.begin(9600);  
     Serial.println("Emartee.Com");  
     Serial.println("Voltage: ");  
     Serial.print("V");
    }
    void loop()
    {      
     float temp;      
     val11=analogRead(1);      
     temp=val11/4.092;      
     val11=(int)temp;//      
     val2=((val11%100)/10);      
     Serial.println(val2);         
     delay(1000);
    }
