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. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000 ppm
Features :

1. Signal output indicator
2. Dual Signals output (analog output and TTL output)
3. The TTL output signal is low level, allows to connect with SCM directly
4. Analog output 0~5V voltage
5. High sensitivity
6. Long working lifetime and stable performance
7. Quick response and recovery.

Product Details:

Features 3 functions in one compact meter-measure the moisture and pH content of the soil and the environmental light. Scientifically accurate. No need for batteries. Easy-to-read scale indicator. Incredibly simple to use - just stick it in the soil! Works with house and garden plants.
Detector shape Needle( 1pc Copper needle, 1pc Silver needle)

• Item Code: PHSOIL

Product Details:

The TCS3200 Colour Sensor Module uses a high quality light sensor allowing you to sense any colour through a combination of Red, Green and Blue.
The module provides all of the pins of the TCS3200 on convenient 0.1" headers - ideal for use with PCBs, breadboard or stripboard.
Four white LEDs provide plenty of light for the colour sensor and allow you to use the module in any ambient light.
The module requires only a single supply voltage between 2.7V and 5.5V - making it compatible with nearly all common microcontrollers, including PICs, AVRs, ARM, Arduino and more!
The pin out is clearly labelled on the board and is as follows:
Header one on the left side of the board:

S0: Output frequency scaling selection input (along with S1)
S1: Output frequency scaling selection input (along with S0)
OE: Output Enable - if held low, the output of the module is turned on
GND: Ground - connect to 0V
Header two on the right side of the board:

• S3: Photodiode type (along with S2)
• S2: Photodiode type (along with S3)
• OUT: Output - A square wave appears here showing the intensity of the detected colour
• VCC: Power - connect to 2.7V-5.5V
• The Photodiode type pins allow you to pick which colour light you are currently detecting:

• S2 S3 Photodiode type
• Low Low Only red light
• Low High Only blue light
• High Low No filter
• High High Only green light
• By combining the reading of each of the three colours, you can identify any visible colour!
