DHT11 Temperature and Humidity Sensor

ZigBee temperature and humidity sensor provides accurate temperature and humidity measurements and stores this data in memory for one year. Broken down into days with hours, months and a year.

The DHT11 humidity sensor is presented in a plastic body ideal for mounting on a panel or similar. It uses a capacitive sensor that returns a digital signal with the measurement.
Characteristic:
- Operating voltage: 3 to 5 VDC - Humidity measurement range: 20-95% ± 5% accuracy
- Temperature measurement range: 0ºC to 50ºC ± 2º accuracy
- Maximum sampling rate: 2 seconds - Working current 2.5mA
- 1-wire interface
- Dimensions: 32 x14 mm
- Quantity: 1 unit with 3x female / female cables

The solar power management module with the CN3065 chip is ideal for IoT (Internet of Things) projects with renewable energy. Compared to the previous version of the module, improvements have been made to the energy management of the connected battery.

The module has two outputs: analog A0 and digital D0
Digital output D0 - signal 0 appears or 1 depending on the threshold setting
The threshold is set with the potentiometer
The sensor can be used for example:
Automatic watering for potted plants
With this module you will be able to measure the humidity of the soil, so that you will be able to control the humidity level of the soil of your plants
Characteristic:
Operation: 3.3V -5V
- Sensitivity adjustable by potentiometer
- Dual output mode: analog and digital
- Red LED - power indicator
- Green LED - indicator digital switching output
- PCB measurements: 3 x 1.5 cm
- Probe measurements: 6 x 3 cm

The DHT22 humidity sensor is presented in a plastic body ideal for mounting on a panel or similar. It uses a capacitive sensor that returns a digital signal with the measurement.
This sensor, unlike DHT11, is capable of measuring negative temperature values ​​and measures tenths of a degree. DHT22/AM2302 Temperature Humidity Sensor features:
- Voltage Operating: 3 to 5.5 VDC
- Humidity measurement range: 0-100% ± 2% accuracy
- Temperature measurement range: -40ºC to 80ºC ± 0.5º accuracy - Maximum sampling rate: 2 seconds
