Program your ESP-01 with this board and an 3.3 V FTDI circuit.
See this 123d Circuits Project for details.

Minimalist Temperature and Humidity Sensor based on the ESP-01/ESP8266 WiFi Board and a DHT22
This board is designed to fit the necessary elements for a ESP8266 & DHT22 Temperature and Humidity Sensor and a 3.3V Voltage Regulator on the smallest footprint possible.
By using the code from https://github.com/tzapu/DeepSleepDHT22, it should be possible to run this sensor off a 3.3V LiPo or two AA 1.5V Batteries for a number of months.
For programming, you’ll need a separate setup. It’s best to use 2x4 female headers on the board, so you can plug-in the ESP-01 instead of soldering it to the board.
Also, if you use Arduino IDE and ArduinoOTA, you can upgrade the software of the ESP-01 over the air.
