DHT11 Temperature and Humidity Sensor

The BME280 is an environmental sensor (SEN0236) integrating a temperature sensor, a humidity sensor and a barometer. Powered from 3.3 V to 5 V with I2C and SPI interface. Measuring range: temperature: -40 °C to 85 °C, humidity: 0 %RH to 100 %RH, pressure: 300 hPa to 1100 hPa.

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.

MS01 works with SONOFF TH10/16 to accurately measure soil moisture and send data to your mobile phone. MS01 can regularly water and check soil moisture anytime and anywhere to make your flowers grow healthier. This is an accessory used in SONOFF TH10 / TH16.

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 SparkFun micro:Climate kit is a complete weather station kit that builds on the weather:bit carrier board with weather and soil moisture sensors, all powered by the micro:bit. board.

The SNZB-02D sensor will monitor temperature and humidity in real time remotely in the application or on the display, with a range of up to 120 metres. The sensor has a built-in intelligent Swiss hygrometer sensor that provides more precise readings, maintaining an accuracy of ±0.2°C/±0.4°F in temperature and ±2% relative humidity in humidity, updating the readings every 5 seconds.

The SparkFun Weather Meter Kit is a set of basic mechanical and electronic components to build a weather station. With the SparkFun Arduino IoT Weather Station kit in sight, you can create your own weather station. The kit allows monitoring via the Arduino Cloud, an IoT platform.

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.

- 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

SONOFF SNZB-02 is an elegant mini wireless intelligent temperature and humidity sensor via ZigBee, through its Bridge(required). Program and create scenes based on the detected values. Maintain a stable temperature in your home.

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
