====== LamaPLC: Humidity / temperature / air-press / gas / air-quality sensors and moduls for Arduino ======

The following tables contain a list of Arduino compatible sensors. The first table lists the sensors in ABC order, together with their technical characteristics.
\\
The second table (modules) contains a list of Arduino compatible sensor modules. In many cases, the voltage level of the sensors is not the same as that of the Arduino (3.3V or 5V). Among other things, the listed modules improve this shortcoming.

===== Arduino compatible sensor modules =====

**Humidity / Temperature Arduino moduls** \\
The temperature / humidity sensor modules contain the additional technology required for sensor ICs (voltage regulation, pull-up resistors,...) and the connection pins simplify the connection of the sensors to, for example, [[arduino:arduino_basic|Arduinos]]. The modules are typically universal and can be used for several sensors, so it's worth paying attention to which sensor is installed on the module, mainly because of the power supply (almost all sensors work with 3.3V, but not all of them work with 5V). There are often bridges used for addressing on the modules, which can be soldered in and out, and for example [[com:basic_i2c|I²C]] addresses can be set with them.

**Gas sensor Arduino moduls** \\
The gas sensor modules contain the additional technology required for sensor ICs (voltage regulation, pull-up resistors,...) and the connection pins simplify the connection of the sensors to, for example, [[arduino:arduino_basic|Arduinos]]. The modules are typically universal and can be used for several sensors, so it's worth paying attention to which sensor is installed on the module, mainly because of the power supply (almost all sensors work with 3.3V, but not all of them work with 5V). There are often bridges used for addressing on the modules, which can be soldered in and out, and for example [[com:basic_i2c|I²C]] addresses can be set with them.

===== Software example =====
The easiest way to find the example program for the current sensor is in the Arduino program in the //"Library Manager"//.

===== Example to oneWire wiring with DHT-11 sensor =====
{{ :sensor:dht11_wiring.png |Example to oneWire wiring - DHT 11 sensor}}
In fact, only one pin is needed to connect oneWire, it can be even the 2nd - there is no rule for this. The supply voltage should be adjusted to the table above, in the case of the **DHT 11** it can be 5V or 3.3V.
