When we are talking about environmental sensors, we always want it to be accurate, and also easy-to-use. Now, we’ve got a really fine sensor module that has both, the Grove - Temperature&Humidity Sensor (SHT31). The SHT31 sensor could be the finest and highest-accuracy humidity sensor you can find, as it can acquire the relative humidity at only ±2% error. On the other side it also features an excellent performance in terms of temperature measurement, you can use it in some extreme conditions, like -40 degree or 125 degree, and it still keeps an accuracy of ±0.3 degree.

This product is a high accuracy temperature and humidity sensor used in home conditions. It consists of a capacitive sensor element used for measuring relative humidity and a negative temperature coefficient (NTC) thermistor used for measuring temperature. Every sensor was calibrated in an accurate humidity room. Small dimension, ultra low power consumption, more than 20m's signal transmission distance make it a good selection for various application environment. Different from Twig - Temp&Humi Sensor v0.9b, the accuracy of this module can gets up to 0.3 degree in temperature and 2% in relative humidity.
Grove - Water Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground and Sensor signals. The sensor traces are weakly pulled up using 1 MΩ resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. This circuit will work with digital I/O pins of Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.

This switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or other devices. When the float ball rises or falls with the liquid to the level of the switch, The magnetic force of magnet which inside of the float ball will cause the reed switch to turn ON. When the float ball move away from the reed switch, the reed switch will turn OFF.
