SONOFF SNZB-04 is a mini sensor for opening and closing doors and windows, intelligent and wireless by ZigBee, through its Bridge. Essential for intruder detection in a home automation system. 

The module has two outputs: analog A0 and digital D0
Digital output D0 - signal 0 appears or 1 depending on the threshold setting
The threshold is set with the potentiometer
The sensor can be used for example:
Automatic watering for potted plants
With this module you will be able to measure the humidity of the soil, so that you will be able to control the humidity level of the soil of your plants
Characteristic:
Operation: 3.3V -5V
- Sensitivity adjustable by potentiometer
- Dual output mode: analog and digital
- Red LED - power indicator
- Green LED - indicator digital switching output
- PCB measurements: 3 x 1.5 cm
- Probe measurements: 6 x 3 cm

Soldering tip cleaner 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.

This module includes the BMP280 component that converts atmospheric pressure, temperature and humidity with high precision into a digital signal.
The equipment uses the two I2C and SPI interfaces. The very good measurements made by the BMP280 allows the module to be used as an altimeter.
Its 5-pin straight connector allows easy connection to other electronic boards. BMP280 Temperature Barometric Pressure Sensor Module/SPI features:
- Interfaces:
       -I2C (up to 3.4 MHz)
       -SPI (up to 10 MHz)
- Supply voltage: 1.8-5VDC
- Module operating range:
       - Temperature: -40ºC to + 85ºC
0-100%
       - Pressure: 300-1100 hPa
- Resolution of the measures:
       - Temperature: 0.01ºC
