Because of their many applications, Pressure, Temperature, and Humidity sensors (PHT sensors) are a common offering from semiconductor companies. The MS8607 PHT sensor from TE Connectivity does an admirable job of measuring a wide range of all three environmental conditions. Each and every MS8607 sensor is calibrated at the factory and the calibration constants stored in the sensor itself. This sensor is a one-stop-shop for all your common weather and environmental-related metrics. Just add an MS8607 and you’ll be ready to finish your enclosure and retire as a Dubia Cockroach Farmer

One standout feature of the MS8607 is it’s very respectable low power consumption at as low as 0.78 µA ! That’s hardly anything! Along with carefully managed microcontroller power usage, getting good battery life out of your sensing project will be that much easier.

While the MS8607 sensor itself is rotund by comparison to some of the other sensors we stock, it’s still a surface mount part so we’ve placed it on a breakout board, nestled amongst a handful of components that take care of level shifting and power regulation. This lets you use it with either 5V or 3.3V devices, so no matter if you have an Arduino, Metro, Feather, or Raspberry Pi, you’ll be able to interface with the MS8607 easily. The breakout has the expected header for power and I2C connections, however, if you prefer to or can’t solder, you can use the Spark Fun Qwiic compatible STEMMA QT connectors to wire up to your favorite micro with a  plug-and-play cable. Even if like me you don’t mind soldering, STEMMA QT connectors are super convenient for wiring up projects quickly. QT Cable is not included, but we have a variety in the shop.

1. The MS8607 provides the previously mentioned factory-calibrated pressure
2. Humidity data are recorded as 16-bit values and made available over an I2C bus for simple

Featutes:

The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity.

But despite its disadvantages over DHT22, it is smaller and less expensive sensor for temperature and humidity measurement.

Note: This package does not include Arduino board, you have to buy it separately.

These Humidity Sensors can be used to detect the environmental relative humidity. Used in many end products such as air conditioners, humidifiers, dehumidifiers, hygrometers, recorders, transmitters.

Most measurement devices usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. From calculations based on physical principles, or especially by calibration with a reference standard, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation, or changes in electrical capacitance or resistance to measure humidity changes.
