Seeed Studio BeagleBone® Green Wireless Development Board(TI AM335x WiFi+BT)

With this small and simple device, you can control your blood oxygen level yourself to avoid going to the doctor or pharmacy on purpose. Simply insert your finger and wait for the reading of haemoglobin (Spo2), heart rate and Perfusion Index (PI%). The heart rate is also graphically displayed. 

You can rotate the screen to see it in its 4 positions. High precision device, with low power consumption and automatic shutdown. 

NTC thermistor - with a negative temperature coefficient, i.e. an increase in temperature causes a decrease in resistance.   Thermistor NTC 50.0K 5% MF52A epoxy resin coating resistor features:

Operating temperature: from -40°C to +125°C  Tinned steel wire 25mm

Level sensor for liquids with float. The liquid level sensor acts as a switch. Liquid level float sensors are used when constant control and regulation of the liquid level (water, oil and other fluids) is required such as extraction pumps. The sensor is equipped with a float with a magnet which, acting by the buoyancy force of the fluid, moves along the tube, shortening or opening the reed switch.

It can be used to detect liquid levels that are too high or too low. Ideal for all those applications where the level of non-corrosive liquids such as water tanks or aquariums needs to be monitored. It is made of stainless steel.

Holder for ultrasonic, distance meter HC-SR04. Ideal for installing the sensor on mobile platforms such as robots, vehicles, etc.

The accelerometer sensor is an add-on for your RedBot that provides shock and motion detection. The sensor works by measuring acceleration forces on the x, y and z axes. By measuring the amount of acceleration (or lack thereof), your robot can better understand its movements.

Sensor used for measuring of the object acceleration in 3 axis in the range of either ±2g, ±4g or ±8g. It is powered with 1.95V to 3.6V. What sets this module apart is its user-friendliness, compatible size and low power consumption. It comes with QWIIC connectors

This photo-resistance module is very sensitive to ambient light. Activation of the microcontroller or retransmission modules,
The brightness module of the ambient light reach the set threshold, the output is high when the ambient light exceeds the set threshold.
The DO output can be connected directly to a microcontroller to detect the light environment and create a light control switch.
It has a speed range of 0% to 100%. Digital Light Intensity Sensor with Photo Resistance with LM393 Controller features:
- Operating voltage: 3.3 - 5 V
- Input current: 50 mA
- Use a very sensitive photo resistance
- Use a LM393 wide voltage comparator, high quality output signal
- Adjustable potentiometer can regulate the brightness of detected light

- Immerse the probe in the fish tank to measure the water temperature Digital Thermometer with External Temperature Probe features:
- Cable length: 1m
- LCD screen
- Temperature range: -50 C ~ + 70C
- Powered by 2 batteries x LR44 / AG13 button (included)
- Cable length: approx.100cm
- External Dimensions: 48 x 28.5 x 15.2 mm
- Dimension LCD screen: 35 x 16 mm
- Color: Black
- Used to measure the temperature in: the rooms, the aquarium, terrarium in the heating system, in the car, fridge, freezer

This air purifier uses a HEPA filter to safely remove viruses, bacteria, mold, mildew, dander, etc. Filters up to 99.5% of dust, pollen, tobacco smoke, mould spores and pet dander. Keeps the environment clean.
