Analogue Ultraviolet (UV) Sensor

John Phillips

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 …

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 …
