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

Ideal to power your Arduino board through the power input.
Adapter Battery 9V 6F22 Jack Connector DC features:
- Cable 7cm long
- Battery connector 9V, 6F22
- Male connector DC 5.5 / 2.5

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.
