CJ1WTS562 (Temperature Sensor Module Screw Terminal Connection)
Highlights/Features:
Omron Temperature sensor module is suitable for use with cj1 series programmer controllers These temperature sensor units are classified as digital I/O units when considering I/O allocations and will take digital I/O points from the total allocation for a CJ1M CPU. The number of I/O points is DIP switch selectable as follows; configured for 1 - 3 inputs takes 48 digital I/O points, configured for 4 inputs takes 64 digital I/O points and configured for 5 - 6 inputs takes 96 digital I/O points.
DHT22- (Temperature and humidity sensor)
Product description:
The DHT22 module is designed to measure the temperature and humidity of the atmosphere. The difference from the younger model (DHT11), The DHT22 has a wide range and a high precision determination of temperature and humidity. The sensor works on the OneWire bus, which makes it possible to connect it to the Arduino only three wires ( two of which are POwer supply). Low power consumption allows you to install it on stand-alone devices.

MQ-8 (Hydrogen Gas Sensor Module)
MQ-8 Sensor Information: sensitive material MQ- 8 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity monitoring of other hydrogen-containing gas is also very good. The sensor can detect a variety of hydrogen-containing gas, in particular, city gas, is a low-cost sensor suitable for a variety of applications.
