The big problem is power at the collection point. Some people use a solar panel and batteries but other options are available
Once you know your power budget you can use a variety of low cost hardware such as Arduino or Nano Pi at the data collection point. There are many sensors available using low complexity connections such as I2C and One-Wire.
For communications you can be really fancy and use full WiFi or you can use a variety of point to point connections such as zigbee
So work out how much power you have and then choose the technology. Most likely it will be arduino, I2C for a combined temperature humidity sensor such as DHT22 AM2302 DHT11/DHT12 AM2320, and matching zigbee modules.
