The SDS011 sensor measures the amount of small polluting particles in the air. It uses a tiny laser to measure the total mass in micrograms per cubic metre of air of two sizes of particles. Called Particulate Matter (PM), one size (PM2.5) has a diameter of 2.5micrometres or less; and the other (PM10) has a diameter of 10 micrometres or …
This sensor measures the distance to an object by using sound waves. Specification Power Supply: 3.3~5.5V DC Operating Current: 20mA Operating Temperature: -10℃～＋70℃ Measurement Range: 2cm～500cm Resolution: 1cm Accuracy: 1% Frequency: 30Hz Max How does it work? It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. This is …
This sensor measures the level of UV radiation in sunlight and creates an output voltage proportional to the UV index. Specification Operating Voltage: 3.3-5V Output voltage: DC 0-1V(Corresponding 0-10 UV index) Operating Current: 0.06mA(0.1mA max) UV wavelength detect: 200-370nm Test accuracy: ±1UV INDEX Response time: <0.5s Operating temperature: -20℃-85℃ How does it work? This sensor operates in the same way …
This is a non-contact IR temperature sensor which uses Infrared radiation to calculate the temperature of something at which it is pointed. Specification Voltage range: 3.3-5V Temperature range: -70 to +380 °C, (0.01 ℃ resolution) Measurement Accuracy: ±0.2℃(body temperature range)/ ±0.5℃ (ambient) Chip: MLX90614 with 17 bit Analogue to Digital (ADC) Converter Required accessary This sensor requires the Pin swap …
This is a waterproofed version of the DS18B20 temperature sensor. It is an INPUT device. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. It is a hybrid analogue/digital device as the analogue temperature …
The DF Robot DHT22 module measures temperature and relative humidity and sends the sampled data digitally to the Kookaberry. The DHT22 has slightly better specifications than the cheaper, but more popular, DHT11 module. Specification (DHT22) Supply Voltage: 3-5 V Temperature Range:-40-80℃ / resolution 0.1℃ / error <±0.5℃ Humidity Range: 0-100%RH / resolution 0.1%RH / error±2%RH Size: 38 x 20 mm …
The DF Robot DHT11 module measures temperature and relative humidity and sends the sampled data digitally to the Kookaberry. The DHT11 is a very adequate performer and is considerably more popular than the slightly better specified and slightly more expensive DHT22 module. Specification (DHT11) Voltage range: 3.3-5 V Temperature range :0-50 °C error of ± 2 °C Humidity :20-90% RH …
The DF Robot Heart Rate Monitor is a thumb-sized sensor that detects the change in blood volume just under the skin and sends either an analogue or digital signal to the connected Kookaberry. There is a small slide switch which changes the output a square digital wave (the default position) to an analogue wave. The Kookaberry Pulse app has been …
The DF Robot ambient light sensor is a photodiode which detects the level of ambient light and sends the value back to the Kookaberry as a proportion of the 3.3v available at the pin interface. FEATURES Wide voltage range from 3.3V to 5V Standard assembling structure (two 3mm holes with multiple of 5cm(1.97″) as interval) High quality connector Immersion gold …
This sensor is an INPUT device. It measures the moisture in a ground medium such as soil. It is an analogue device. The principles of Electrolysis and Electroplating can also be demonstrated by observing that the metal coating of one of the prongs deteriorates over time. Specification Power supply: 3.3v or 5v Output voltage signal: 0~4.2v Current: 35mA Size: 60x20x5mm …
