hi all of you
I must use 100 YL-69 module in a garden.
Can i connect 100 YL-69 to one Arduino UNO ?

Thanks dear friend
I have no problem using this sensor and I have used it many times.
My current problem is that I have to manage 100 of these sensors.
How do I make connections?
How do I get the information?
How do I know which sensor the received information belongs to?

The simple answer is NO.
You need 100 input pins digital or 100 input pins analog.
OR you need a bus system or a wireless system to transmit the data.
Bus system, where all sensors are conected by wire should be Can-Bus
With wireless you must decide depending on how big area you should cover.
Each sensor connects to an Esp8266 or Uno and then
1. Use WiFi (Short reach)
2. Connect a transmitter. (Longer reach) https://www.b4x.com/android/forum/threads/rf24-nrf24l01-radio-modules.66972/
3. Connect a Lora transmitter. (Longest reach) https://www.b4x.com/android/forum/threads/rradiohead-rf95-dragino-lora-shield.86819/#content

For more GPIO Pins @inakigarm (I think) had suggested to me to use MCP23017 with I2C interface or MCP23S17 with SPI communication interface.

1. you need A/D Multiplexing, e.g with CD74HC4067. Here are 5pcs for a few bugs.
5PCS 16CH Analog Digital MUX Breakout Board CD74HC4067 Precise Module Arduino | eBay
This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching.

2. Create clusters of sensors with your favourite microcontroller.
A cluster consists of e.g. 10 sensors then you need 10 microcontrollers.
Each cluster has its own microcontroller that fetches the sensor values or processes them directly.
Whether wireless or wired depends on the local conditions.
