Keyes 37 sensor kit is a great extension set for your Micro:Bit. Using Sensor shield for Micro:Bit you can connect all modules included in the pack only by the connectors without soldering or wiring any parts. Now you can concentrate only on programming with your big Mirco:Bit.

It allows removing the solder residues from the tips.
It cleans better and does not cause temperature drops like with sponges.
You do not need extra water to clean the tip.
Easy and effective cleaning at the tip.
Soldering Tip Cleaning Ball features:
- Dimensions: diameter 50mm

Ethanol alcohol sensor module.
MQ gas sensor uses a small indoor heater with an electrochemical sensor.
When the alcohol molecules in the air comply with the electrode the ethanol "changes" into acetic acid and then more current is produced.

- Main chip: alcohol sensor MQ-3 and comparator LM393
- Working voltage: 5V
- Current: 150mA
- Digital output: TTL 0/1
- Analog output: analog voltage sensing value
- Detection concentration:
- 0.05mg/L - 10mg/L
- Quick response features:
- Adjustable sensitivity with the potentiometer
- Size: 32mm x 20mmx 18mm

Rechargeable Battery Samsung INR18650 2500mAh Li-ion 3.7V 20A unprotected features:
IMPORTANT: This battery does not have a protection circuit.
Use it at your own risk.
Do not charge over 4.2V
Do not discharge below 3V
Do not change polarity
Do not heat the battery, or expose it to high temperatures
Do not wet or expose to environments of High humidity
For long periods of storage it should be stored below 45 ° C
After long periods of storage you will probably need to do some charging cycles to increase the capacity again.
