DS18B20

John Phillips

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 …

DHT22

John Phillips

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 …

DHT11

John Phillips

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 …

Heart rate monitor

John Phillips

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 …

Ambient Light Sensor

John Phillips

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 …

Soil Moisture Sensor (Resistive)

John Phillips

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 …
